[oXygen-user] webhelp search not finding some words

We are testing the webhelp feature of Oxygen 14.2. Mostly it seems really good. The search feature seems great: fast, no server-side requirements, hightlighting, etc. But in quick testing we have found a few words that are in the content that don't turn up in search results: 'dashboard', 'account', 'define' and 'definition'. The words are in topics and generated index files seem to properly include the terms (index-1.js, htmlFileInfoList.js). Anyone know what could be going on? We are a little worried as we don't know how widespread the problem may be.
