PDF Index

Build a reusable search index (pdf-index)

Build a reusable search index

Part of the Universal PDF Management & Creation Skill Repository. Category: PDF Management. Every skill is individually callable (INDIVIDUAL MODE) and may also be invoked automatically by the orchestrator (SYSTEM MODE).

When to use

For huge or repeatedly-queried documents, index once then retrieve fast.

Operations

• positional term index
• page-level inverted index
• persisted JSON
• reuse across queries without re-parsing

Engine (what actually executes this)

universal_pdf/core.search:build_index

All heavy lifting is done on disk / one page at a time by the shared engine — never by loading the document into an LLM context.

Tools & graceful degradation

• Preferred tool: positional inverted index (JSON)
• Fallback: SQLite/DB backend for huge corpora

If the preferred backend is unavailable the skill transparently uses the fallback or reports a documented limitation. It never reports success when an operation did not actually happen.

Validation (this skill attaches checks to its Outcome)
