ConfigurationParameters

ConfigurationParameters()

The production configuration, as a fresh instance: every setting taken from its own type's. Equal toin every respect but identity, so preferunless you specifically want your own object.

ConfigurationParameters(IndexerSetup indexer)

The indexing strategy of your choice, everything else as shipped. The short form of the common case: the indexer is the part worth varying, and the tokenizer, normalizer and word matcher rarely are.

• IndexerSetup indexer — How text becomes index entries.,or- or one of those passed through.

ConfigurationParameters(IndexerSetup indexer, TokenizerSetup tokenizerSetup, TextNormalizer textNormalizer, WordMatcherSetup wordMatcherSetup, int filterCacheSize = 200000)

Builds a configuration from its parts. Every setup object must be stated - passfor the ones you do not care about, which is shorter and safer than copying their values out by hand.

• IndexerSetup indexer — How text becomes index entries.,for small corpora, orfor code and identifier lookup.
• TokenizerSetup tokenizerSetup — DefaultWord-token delimiters and sizes.is the 20-delimiter production set. Note thatis a single space delimiter, NOT the default.
• TextNormalizer textNormalizer — DefaultDiacritic folding and string replacement.folds the full table; one built with empty tables folds nothing, which is how normalization is turned off.
• WordMatcherSetup wordMatcherSetup — DefaultFuzzy matching at search time.enables LD1 and affix matching;supports nothing and is how it is turned off.
• int filterCacheSize — DefaultFilterCacheSizeFilter cache entries. Omit for. Below the number of live filter keys the cache starts evicting and rebuilding them on next use.

ConfigurationParameters(IndexerSetup indexer, TokenizerSetup tokenizerSetup, TextNormalizer textNormalizer, WordMatcherSetup wordMatcherSetup, EmbeddingSetup embeddingSetup, int filterCacheSize = 200000)

DefaultAs the constructor above, with how vector fields are held stated too. The one above takes: an overload, and not one more required argument, so that the many configurations written before vector fields had settings (Oct 2026) keep compiling and keep meaning what they meant.

• IndexerSetup indexer — As above.
• TokenizerSetup tokenizerSetup — As above.
• TextNormalizer textNormalizer — As above.
• WordMatcherSetup wordMatcherSetup — As above.
• EmbeddingSetup embeddingSetup — DefaultHow vector fields are held and searched.keeps the search graph's vectors as 16-bit integers.
• int filterCacheSize — As above.

TokenizerSetup(Char delimiter =  )

• Char delimiter — Default:

TokenizerSetup(Char[] delimiters, bool highResolutionMode, int minimumWordSize = 2)

• Char[] delimiters
• bool highResolutionMode
• int minimumWordSize — Default: 2

TextNormalizer(ValueTuple<string, string>[] stringReplacements, ValueTuple<Char, Char>[] charReplacements, bool oneWayMode)

• ValueTuple<string, string>[] stringReplacements
• ValueTuple<Char, Char>[] charReplacements
• bool oneWayMode

TextNormalizer(StringReplacer stringReplacer, CharReplacer charReplacer)

Rebuilds a normalizer from its two replacers. This is the shape a normalizer is written out as, so it is mainly the deserialization path rather than something to call by hand — prefer the tuple constructor above.

• StringReplacer stringReplacer — The string-replacement half; null means a normalizer that does not do string replacement.
• CharReplacer charReplacer — The character-folding half; null means a normalizer that does not fold characters.

WordMatcherSetup(int MaximumWordSizeExact = 8, int MaximumWordSizeLD1 = 8, int MinimumWordSizeExact = 2, int MinimumWordSizeLD1 = 3, bool SupportLD1 = false, bool SupportAffix = false)

Fuzzy word matching at search time: whether a query word may match an indexed word it does not equal, and within which word lengths.

• int MaximumWordSizeExact — Longest word eligible for exact matching. Past this a word is matched by the index's pattern matching alone.
• int MaximumWordSizeLD1 — MaximumWordSizeExactLongest word eligible for edit-distance-1 matching. Keep at or below.
• int MinimumWordSizeExact — Shortest word eligible for exact matching.
• int MinimumWordSizeLD1 — Shortest word eligible for LD1. Higher than the exact minimum on purpose: at three characters, one edit reaches a large share of the vocabulary and the match stops meaning much.
• bool SupportLD1 — Allow a one-edit difference — insertion, deletion or substitution — so a typo still finds the word. The forgiving half, and the expensive half.
• bool SupportAffix — Allow a match on a word that extends the query word, so "fish" reaches "fishing". Prefix-style matching for word tokens.

CharReplacer(ValueTuple<Char, Char>[] replacements, bool oneWayMode)

• ValueTuple<Char, Char>[] replacements
• bool oneWayMode

CharReplacer(Char[] toBeReplaced, Char[] replaceBy, bool oneWayMode)

• Char[] toBeReplaced
• Char[] replaceBy
• bool oneWayMode

StringReplacer(string[] toReplace, string[] replaceBy)

• string[] toReplace
• string[] replaceBy

StringReplacer(ValueTuple<string, string>[] replaceMents)

• ValueTuple<string, string>[] replaceMents
