Hi Colin, Is it possible that you are using an analyzer that breaks words on non letters? For instance SimpleAnalyzer? if so, the doc text: pagefile.sys is indexed as two words: pagefile sys At search time, the query text: pagefile.sys is also parsed-tokenized into a two words query: profile sys but the query text: pagefile.sys* is not analyzed (by design) and matches only words that start with: pagefile.sys But there are no such words in the index, because it was indexed with breaking words on non-letters...
Hopefully this gets you started... If this is the reason, you may want to use a different analyzer (See Wiki page "AnalysisParalysis"). Otherwise, make sure you use the same analyzers at indexing and search ... and see the Lucene FAQ entry "Why am I getting no hits / incorrect hits?". If all this still fails, try to post here a simple code snippet showing how you index and how you search.
