Hi there, It looks alot like using Solr's standard "WordDelimiterFilter" (see the sample schema.xml) does what you need. It splits on alphabetical to numeric boundaries and on the various kinds of intra word delimiters like "-", "_" or ".". You can decide whether the parts are put together again in addition to the split up tokens. Control this by the parameters "catenateWords", "catenateNumbers" and "catenateAll". Good documentation on this topic is found on the wiki

Use that both at index and search time. For example: * 3555LHP becomes "3555" "LHP" Searching for D3555 becomes "D" OR "3555", so it matches on token "3555" from 3555LHP. * t14240 becomes "t" "14240" Searching for t14240-ss becomes "t" OR "14240" OR "ss", matching "14240" from "t14240". Similarly for your other examples. If this proves to be too broad, you may need to define some stricter rules, but you could use this for starters. I think you will have to write your own analyzer, as it doesn't look like any of the analyzers available in Solr/Lucene do exactly what you need. But that's relatively straightforward. Just start with the code from one of the existing Analyzers (e.g. KeywordAnalyzer).
