Approximate Phrase Index Matcher (Labs)

The Approximate Phrase Index Matcher node compares each phrase in the Comparison Table to phrases stored in a prebuilt Index Object (from Phrase Indexer).
It uses exorbyte’s deterministic, subword-aware engine to compute fuzzy similarity over multi-word strings.
Optionally, an Alias Object can expand the search with synonymous, canonical, or normalized forms (e.g., "NYC" ⇄ "New York City"), improving recall without sacrificing determinism.
This node is suited for entity normalization, product/title matching, review/snippet clustering, and duplicate detection. It can emit scores, alignment sequences, hit coverage, and best-match candidates, and it can filter rows by threshold.

Add Column with Character Match Sequence

Adds a symbolic alignment string visualizing matching and mismatching characters.
'=' -> Match
'x' -> Mismatch
'+' -> Insertion
'/' or '\' -> transition

Add Column with Hit Characters Sequence

Appends a column showing which parts of the reference phrase were matched by the comparison.

Add Column with Best Reference Match

Appends the most similar reference phrase for each comparison row, identifying the best match candidate.

Row Filter Condition

Controls which rows are included in the node output based on the match result.
Options:

• Output matching rows - Only outputs rows that meet or exceed the similarity threshold.
• Output non-matching rows - Only outputs rows that do not meet the threshold.
• No Filtering - Outputs all rows with match metadata for analysis.

Matching Value Threshold - Minimal Matching Percentage

This setting allows you to set the filter criteria based on Match Quality.
This setting only appears if filtering is actually switched on by the previous setting.
