* [MM-24529] Preserve hyphenated compound words in Postgres search Postgres full-text search stripped every hyphen to a space before building a to_tsquery, so an unquoted search for "t-shirt" degraded into a loose "t AND shirt" match instead of the compound-word match the quoted version already got. Fix is Postgres-only; MySQL is gone and Elasticsearch/Bleve use a different tokenizer/query mechanism (verified empirically against a live ES instance - out of scope here). - Remove "-" from the shared specialSearchChars strip list in store.go, and add neutralizeNonWordHyphens (utils.go), which keeps a hyphen only when flanked by a letter/digit on both sides, neutralizing malformed usage (leading/trailing/standalone/repeated) that would otherwise reach to_tsquery as a parse error. - Wire the new helper into post_store.go's tsquery-building path. - file_info_store.go keeps the old hyphen-to-space behavior: real filenames glue a hyphenated name directly to an extension (e.g. "photo-2024.jpg"), which Postgres's parser tokenizes as an opaque "host"-type token that a hyphen-preserving compound query can never match - verified against Postgres. Re-skip the two FileInfo dash acceptance tests with an accurate reason instead of "Not working". - Re-enable the two previously-skipped Postgres post-search dash acceptance tests, and extend them with excluded-term, wildcard, and letters-digits-compound cases. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Revert file_info_layer.go changes Restore the two FileInfo dash acceptance tests to their original Skip:true/SkipMessage state, matching master exactly. The underlying fix (file_info_store.go keeps the old hyphen-to-space behavior since Postgres tokenizes hyphenated-filename+extension as an opaque token) is unaffected - this only reverts the test scaffolding tweak.
