Hi, First of all I tried to find here at http://mail-archives.apache.org/mod_mbox/lucene-java-user/ to see if this question is asked already but I don't know how to do search there. Let me know if there's easier way to search previously asked questions on the forum. My problem is I am trying to match multiple data sets and match them according to different fields. One of the field is COmpany Name. Same company name is presented differently in different data sets and possibly duplicated with similar entries. I am planning to use standard analyzer to index biggest data set and use other data sets to form boolean query for match. Question is is there any filter, stemmer implemented for Business Names taxonomy that I should use? Thanks
