Hi, We have been using SimpleAnalyzer which keeps only letters in its tokens. This limits us to search in strings that contains both letters and numbers. For e.g. "axt1234". SimpleAnalyzer would only enable us to search for "axt" successfully, but search strings like "axt1", "axt123" etc would give no results because while indexing it ignored the numbers.
I can use StandardAnalyzer or WhitespaceAnalyzer but I want to tokenize on underscores also which these analyzers don't do. I have also looked at WordDelimiterFilter which will split "axt1234" into "axt" and "1234". However, using this also, I cannot search for "axt12" etc. Is there something like an Alphanumeric analyzer which would be very similar to SimpleAnalzyer but in addition to letters it would also keep digits in its tokens? I am willing contribute such an analyzer if one is not available. Thanks and Regards, Abhishek
