Why not index into different fields based upon the file type? That would be MUCH easier and PerFieldAnalyzerWrapper would be your friend. For example.....
Doc1 text_html: "some text here" type: html Doc2 text_jsp: "some jsp text here' type: html etc... Now your PerFieldAnalyzerWrapper has your html extractor for the text_html field and your jsp extractor for the text_jsp field. Searching would require you to search across all your different types, but that's do-able. Or you'd have to restrict your searching to one of the text_* fields if you really only wanted to search that type. But I still think you're not clear on the difference when searching. Your search query analyzer will probably have no relation to your indexing analyzer since the type of input is irrelevant to your query (I guess anyway). There you're probably using one of the analyzers provided out of the box.
