Translation Memory

Search translation memory (sync)

Overview

Searches a single translation memory using the primary TM scoring pipeline. The endpoint always returns up to 15 SearchTMResponseDto entries ordered by score.

Modes

Standard segment search (default): normalize text, leverage penalties, thresholds, tag metadata, and context. This is the behavior when phraseQuery=true(default). The service calls the downstream /search endpoint with wildcard=true to allow combined exact/wildcard candidates in one pass.
Legacy phrase-only mode: set phraseQuery=false to disable the wildcard branch (wildcard=false, exactIfQuotes=false, combinedExact=false). Use when you need strict normalized matches without wildcard processing.

Request parameters

query (required): search text. If trimQuery=true (default) leading/trailing whitespace is removed before sending to TM service.
sourceLang (required) and optional targetLangs: locales are normalized. When targetLangs is omitted the backend queries all TM targets.
previousSegment / nextSegment: optional context strings; when provided, the backend raises 101% matches that align with the surrounding segments.
tagMetadata: serialized inline tags; improves scoring and avoids dropping tag pairs.
trimQuery: default true. Set to false to preserve leading/trailing spaces (rare).
phraseQuery: default true. Controls whether wildcard/phrase helpers are enabled (see “Modes”).

Scoring & ordering

Backend computes grossScore (raw similarity) and score (penalty-adjusted). 101% matches retain their priority even after penalties.
Ordering priority (per downstream service): score DESC, grossScore DESC, context match priority DESC, segment key ASC, TM priority ASC, timestamp DESC, TU id DESC.
Numeric replacements or uppercase normalization are not performed here (replaceFigures=false, modifyTransText=false in this controller).

Limits & behavior

Returns maximum 15 matches; there is no offset or totalFoundCount.
Threshold is fixed to 0, so all results above penalties are returned until limit.
Multiple target locales per TM are not supported, mirroring backend validation.
Logical operators (AND/OR/NOT) and wildcard expressions in query are interpreted only when phraseQuery=true enables the wildcard path.

Context & caching notes

Downstream service may consult its 60-second cache for identical search inputs (including context and penalties). Freshly imported matches might appear with a short delay if cached results are reused.
If previous/next segments are omitted the search still runs, but 101% context boosts cannot trigger.

Error handling

Invalid locales, blank query, or an inaccessible TM ID return 400/403.
Backend may throw when multiple target locales are submitted for a single TM; the controller surfaces that error unchanged.
