Hey all, The standard solution to doing a case-insensitive match in lucene is to use a Lowercase filter at index and query time. However this does not preserve the content of the original document. For example if my inverted index is.
Term Doc_1 Doc_2 ------------------------- Quick | | X The | X | brown | X | X dog | X | dogs | | X fox | X | foxes | | X in | | X jumped | X | lazy | X | X leap | | X over | X | X quick | X | summer | | X the | X | ------------------------ Is it possible to choose between case insensitive/ case sensitive match at query time. The index is stored in memory in solr. My question is, if this is stored as a hashmap with string key can I override the hashcode so that "Quick" and "quick" return the same hash value? Has anyone attempted this before? Is my assumption about index right? What would be the classes and code flow to look at? -- Regards, Apurv
