# Search Strategy

> If you see unfamiliar placeholders or need to check which tools are connected, see [CONNECTORS.md](../../CONNECTORS.md).

The core intelligence behind enterprise search. Transforms a single natural language question into parallel, source-specific searches and produces ranked, deduplicated results.

## The Goal

Turn this:
```
"What did we decide about the API migration timeline?"
```

Into targeted searches across every connected source:
```
~~chat:  "API migration timeline decision" (semantic) + "API migration" in:#engineering after:2025-01-01
~~knowledge base: semantic search "API migration timeline decision"
~~project tracker:  text search "API migration" in relevant workspace
```

Then synthesize the results into a single coherent answer.

## Query Decomposition

### Step 1: Identify Query Type

Classify the user's question to determine search strategy:

| Query Type | Example | Strategy |
|-----------|---------|----------|
| **Decision** | "What did we decide about X?" | Prioritize conversations (~~chat, email), look for conclusion signals |
| **Status** | "What's the status of Project Y?" | Prioritize recent activity, task trackers, status updates |
| **Document** | "Where's the spec for Z?" | Prioritize Drive, wiki, shared docs |
| **Person** | "Who's working on X?" | Search task assignments, message authors, doc collaborators |
| **Factual** | "What's our policy on X?" | Prioritize wiki, official docs, then confirmatory conversations |
| **Temporal** | "When did X happen?" | Search with broad date range, look for timestamps |
| **Exploratory** | "What do we know about X?" | Broad search across all sources, synthesize |

### Step 2: Extract Search Components

From the query, extract:

- **Keywords**: Core terms that must appear in results
- **Entities**: People, projects, teams, tools (use memory system if available)
- **Intent signals**: Decision words, status words, temporal markers
- **Constraints**: Time ranges, source hints, author filters
- **Negations**: Things to exclude

### Step 3: Generate Sub-Queries Per Source

For each available source, create one or more targeted queries:

**Prefer semantic search** for:
- Conceptual questions ("What do we think about...")
- Questions where exact keywords are unknown
- Exploratory queries

**Prefer keyword search** for:
- Known terms, project names, acronyms
- Exact phrases the user quoted
- Filter-heavy queries (from:, in:, after:)

**Generate multiple query variants** when the topic might be referred to differently:
```
User: "Kubernetes setup"
Queries: "Kubernetes", "k8s", "cluster", "container orchestration"
```

## Source-Specific Query Translation

### ~~chat

**Semantic search** (natural language questions):
```
query: "What is the status of project aurora?"
```

**Keyword search:**
```
query: "project aurora status update"
query: "aurora in:#engineering after:2025-01-15"
query: "from:<@UserID> aurora"
```

**Filter mapping:**
| Enterprise filter | ~~chat syntax |
|------------------|--------------|
| `from:sarah` | `from:sarah` or `from:<@USERID>` |
| `in:engineering` | `in:engineering` |
| `after:2025-01-01` | `after:2025-01-01` |
| `before:2025-02-01` | `before:2025-02-01` |
| `type:thread` | `is:thread` |
| `type:file` | `has:file` |

### ~~knowledge base (Wiki)

**Semantic search** — Use for conceptual queries:
```
descriptive_query: "API migration timeline and decision rationale"
```

**Keyword search** — Use for exact terms:
```
query: "API migration"
query: "\"API migration timeline\""  (exact phrase)
```

### ~~project tracker

**Task search:**
```
text: "API migration"
workspace: [workspace_id]
completed: false  (for status queries)
assignee_any: "me"  (for "my tasks" queries)
```

**Filter mapping:**
| Enterprise filter | ~~project tracker parameter |
|------------------|----------------|
| `from:sarah` | `assignee_any` or `created_by_any` |
| `after:2025-01-01` | `modified_on_after: "2025-01-01"` |
| `type:milestone` | `resource_subtype: "milestone"` |

## Result Ranking

### Relevance Scoring

Score each result on these factors (weighted by query type):

| Factor | Weight (Decision) | Weight (Status) | Weight (Document) | Weight (Factual) |
|--------|-------------------|------------------|--------------------|-------------------|
| Keyword match | 0.3 | 0.2 | 0.4 | 0.3 |
| Freshness | 0.3 | 0.4 | 0.2 | 0.1 |
| Authority | 0.2 | 0.1 | 0.3 | 0.4 |
| Completeness | 0.2 | 0.3 | 0.1 | 0.2 |

### Authority Hierarchy

Depends on query type:

**For factual/policy questions:**
```
Wiki/Official docs > Shared documents > Email announcements > Chat messages
```

**For "what happened" / decision questions:**
```
Meeting notes > Thread conclusions > Email confirmations > Chat messages
```

**For status questions:**
```
Task tracker > Recent chat > Status docs > Email updates
```

## Handling Ambiguity

When a query is ambiguous, prefer asking one focused clarifying question over guessing:

```
Ambiguous: "search for the migration"
→ "I found references to a few migrations. Are you looking for:
   1. The database migration (Project Phoenix)
   2. The cloud migration (AWS → GCP)
   3. The email migration (Exchange → O365)"
```

Only ask for clarification when:
- There are genuinely distinct interpretations that would produce very different results
- The ambiguity would significantly affect which sources to search

Do NOT ask for clarification when:
- The query is clear enough to produce useful results
- Minor ambiguity can be resolved by returning results from multiple interpretations

## Fallback Strategies

When a source is unavailable or returns no results:

1. **Source unavailable**: Skip it, search remaining sources, note the gap
2. **No results from a source**: Try broader query terms, remove date filters, try alternate keywords
3. **All sources return nothing**: Suggest query modifications to the user
4. **Rate limited**: Note the limitation, return results from other sources, suggest retrying later

### Query Broadening

If initial queries return too few results:
```
Original: "PostgreSQL migration Q2 timeline decision"
Broader:  "PostgreSQL migration"
Broader:  "database migration"
Broadest: "migration"
```

Remove constraints in this order:
1. Date filters (search all time)
2. Source/location filters
3. Less important keywords
4. Keep only core entity/topic terms

## Parallel Execution

Always execute searches across sources in parallel, never sequentially. The total search time should be roughly equal to the slowest single source, not the sum of all sources.

```
[User query]
     ↓ decompose
[~~chat query] [~~email query] [~~cloud storage query] [Wiki query] [~~project tracker query]
     ↓            ↓            ↓              ↓            ↓
  (parallel execution)
     ↓
[Merge + Rank + Deduplicate]
     ↓
[Synthesized answer]
```

Overview

This skill orchestrates multi-source enterprise search by decomposing a natural language question into targeted, source-specific queries and returning a ranked, deduplicated synthesis. It translates user intent into the right mix of semantic and keyword searches, executes them in parallel, and applies relevance and authority heuristics to surface the best answers. It also handles ambiguity and fallback strategies to ensure robust results when sources are missing or queries are unclear.

How this skill works

The skill classifies the query type (decision, status, document, person, factual, temporal, exploratory) and extracts keywords, entities, intent signals, constraints, and negations. It then generates tailored sub-queries per connected source (chat, knowledge base, project tracker, cloud storage), choosing semantic or keyword search and mapping enterprise filters to source-specific syntax. Searches run in parallel, results are merged, scored by relevance/authority/freshness, deduplicated, and synthesized into a single coherent answer. When ambiguity or failures occur, it asks focused clarifying questions or applies fallback broadening rules.

When to use it

  • You need a single answer synthesized from chat, docs, and trackers
  • You want to find decisions or conclusions across conversations and meeting notes
  • You need status or task updates across project trackers and chats
  • You want authoritative policy or documentation surfaced quickly
  • The query is exploratory and benefits from semantic search across sources
  • A source returned no results or is temporarily unavailable

Best practices

  • Prefer semantic search for conceptual or exploratory queries and keyword search for exact names and filters
  • Always extract entities, time constraints, and negations before generating sub-queries
  • Run source queries in parallel to minimize latency and merge results centrally
  • Rank results using a query-type weighted relevance model (keywords, freshness, authority, completeness)
  • Ask one concise clarifying question only when distinct interpretations would change results substantially
  • When sources are unavailable, explicitly note gaps and broaden queries in a defined order (remove date, remove location, relax keywords)

Example use cases

  • User: "What did we decide about the API migration timeline?" → searches chats, meeting notes, tracker tasks, and docs; returns prioritized decision evidence and links
  • User: "What's the status of Project Aurora?" → pulls recent tracker updates, recent chat mentions, and status docs to synthesize current progress and blockers
  • User: "Where's the spec for feature X?" → searches wikis, drives, and shared docs with exact-phrase and semantic variants and returns authoritative doc links
  • User: "Who's working on the billing migration?" → checks task assignees, recent commit/authorship, and chat mentions to list likely owners and confidence levels

FAQ

How does the skill decide between semantic and keyword search?

It prefers semantic search for conceptual or exploratory queries and keyword search for exact project names, quoted phrases, or filter-heavy queries; it may issue multiple variants when needed.

What happens if a source is unavailable or returns no results?

It skips the unavailable source, searches remaining sources in parallel, notes the gap in the synthesis, and applies query-broadening (remove date, relax keywords) or suggests query edits to the user.
