Assembly

"Did you mean?" spelling correction. Delegates to SpellIndex which uses a pre-built character-trigram inverted index for fast candidate filtering, then scores by docFreq / (1 + editDistance). The SpellIndex is cached per searcher/field pair and released when the IndexSearcher is collected.

Methods

Suggest(IndexSearcher, string, string, int, int)

Suggests corrections for queryTerm in the given field. The underlying SpellIndex is built once per searcher/field pair and cached for subsequent calls. For explicit control over the index lifecycle, use Suggest(SpellIndex, string, int, int) with a manually built index.

Suggest(SpellIndex, string, int, int)

Suggests corrections using a pre-built SpellIndex. Use this overload when issuing multiple suggestions against the same index to avoid rebuilding the trigram index on every call.
