On some navigator panes there's a possibility to search for any word anywhere in content. Such full-text search, depending on what's installed on your system, may be performed by the Exalead or SQL full-text search engine.

How to find out if a field is full-text search?

A full-text search field has typical options such as All, Some, Near, Exact, ButNot, Soundslike etc. To reveal options, click the button next to the search field (if available).
