functional-search

Search functional specification markdown files with hybrid ranked search.

Parse $ARGUMENTS to extract the query, optional path, and flags.

If the arguments contain en or in, split on the last occurrence to get query and path. Strip surrounding quotes from path.

Run the search (portable script resolution, do not hardcode a single home path):

SCRIPT_PATH=""
for p in \
  "./scripts/functional_search.py" \
  "$HOME/.agents/skills/functional-search/scripts/functional_search.py" \
  "$HOME/.codex/skills/functional-search/scripts/functional_search.py" \
  "$HOME/.claude/skills/functional-search/scripts/functional_search.py"
do
  [ -f "$p" ] && SCRIPT_PATH="$p" && break
done

if [ -z "$SCRIPT_PATH" ]; then
  echo "functional-search script not found in local repo or known skill install paths" >&2
  exit 1
fi

# If path was provided:
python3 "$SCRIPT_PATH" "<query>" --path "<path>" [flags]

# If path was not provided:
python3 "$SCRIPT_PATH" "<query>" [flags]

The engine automatically combines BM25 ranking, exact phrase boost, section-title boost, proximity boost, and NOT filtering. No modes needed.

Query syntax (all automatic):

• Bare words: filtros contenido wells — ranked by relevance
• "Quoted phrases": "well content" — exact match boosted
• NOT: compound NOT solvent — excludes lines with those terms
• Natural language: cómo se filtran los wells por compuesto — just works
• Combined: "well content" compound NOT image — all features together

Structural commands:

• --toc → add --toc flag
• --section "<name>" → add --section "<name>" flag
• --stats → add --stats flag

Use --format json for programmatic output, --max-results N to limit, --context N for surrounding lines.

Default path: current working directory (all .md files recursively).

Present results grouped by file > section breadcrumb, with scores. For large result sets, summarize which sections matched first.
