documentation on Lucene

Hello folks, I am new to Lucene search engine. I have read about the power of Lucene in indexing and search. I just browsed through the site http://jakarta.apache.org/lucene to find about the documentation on Lucene classes. But I was unable to find the required information(about the abstract

storing index in third party database.

Hi all I want to index the datas which I already stored in a thirdparty database table and develop a search facility using lucene. I am thinking of storing this indexes back to the database in another table. I know for this we have to create a 'directory' which do all the indexing operations,

JavaCC 2.1 works, too. This is how I have it set up: [otis@linux2 otis]$ ls -al /usr/local/.version/javacc2.1/ total 44 drwxrwxr-x6 otis otis 4096 Jan 28 06:50 . drwxr-xr-x 20 otis otis 4096 Apr 2 23:32 .. drwxrwxr-x3 otis otis 4096 Jan 28 06:50 bin

Re: storing index in third party database.

Objects as search results

Here's a topic which to my recollection (surprisingly) hasn't been brought up: Assuming development in an object-oriented environment, it's a fair assumption that the eventual target of searching is an object. How are developers making this happen? Are all fields of the objects indexed and
