*> 1) If the content of indexAnalyzer and queryAnalyzer are exactly the same,that's the same as if I have an analyzer only, right?* 1) Yes
*> 2) Under the hood, all three are the same thing when it comes to what kind* *of data and configuration attributes can take, right?* 2) Yes. Both take in text and output a token stream. *>What I'm trying to figure out is this: beside being able to configure a* *fieldType to have different analyzer setting at index and query time, thereis nothing else that's unique about each.* The only thing to look out for in Solr land is the query parser. Most Solr query parsers treat whitespace as meaningful. For example, if a user searches for q=hot dogs&defType=edismax&qf=title body the *query parser* *not* the *analyzer* first turns the query into: (title:hot title:dog) | (body:hot body:dog) each word which *then *gets analyzed. This is because the query parser tries to be smart and turn "hot dog" into hot OR dog, or more specifically making them two must clauses. This trips quite a few folks up, you can use the field query parser which uses the field as a phrase query.
