Hi thanks for getting back to me so quickly So to give some context, there are two things we would like to be able to do:
1. We want to have the option to be able to search on terms that include punctuation. So for example, if we have the two texts: "they sent an S.O.S from", and "she wrote SOS, but she meant Soz", the user may want to search for the acronym of 'Save our Souls', which would be "S.O.S", and in this instance they only want to match the first text, i.e. "they sent an S.O.S from", and not the second. 2. We want to have the option to make our searches case-sensitive. By default, I think in Lucene with the StandardAnalyzer everything is converted to lower-case at both index and search time. Instead we want upper/lower case to be important, so that for example the texts "Hello said bob", "mike says hello to bob", "The project HeLlO" and "HELLO is the acronym for" are all different texts, and if the user were to search for "Hello" they would only match one of the texts, i.e. "Hello said bob". Does that help?
