+For general text search across all text fields and titles, matches are based only on the beginning of a word, not any part of it.
+For example, if the issue title is **"Document full-text search"**:

+* **Doesn't match**: "cument", "ext", "arch"
+
+This approach helps keep general text search more precise and relevant.

 You can also use a <code>&ast;</code> as a wildcard.
