: are there any APIs which will index mysql databases and run periodically ?
I'll defer that question to someone else who knows more about it.
: i have one more query: if i choose to search on multiple fields do i loose
: the advantage of fuzzy search and stuff like that
Absolutely not. Searching on multiple fields can be done with a
BooleanQuery, which allows you to compose multiple queries, each
"Sub-Clause" being either optional, required, or mandatory. When building
up a BooleanQuery, the clauses can be term queres, or wild card queries or
any other type of query you want.
expressed in a "standard QueryParser syntax" you can easily do the
following...
+title:Java author:Erik~ -category:Coffee
...which means find all documents where the title contains the word "Java"
and category does not contain the word "Coffee". Documents with a word in
the author that has a fuzzy match on "Erik" will get higher scores.
More info on the QueryParser syntax can be found here...
