Finding the position of search hits from Lucene
Hello
How can I find and save the position of search hits from Lucene ?..
Like this:

...
doc 100: 100
I use lucene 3.0
Thank U
Titus

Surely that is what you've got if you use the scoreDocs array as Simon
suggests. Zero based of course.

Can't you simply use the TopDocs#scoreDocs array to figure out the
ranked position and the doc Id?!

Do you mean the positions where a particular term occurred in a document?
If so you should look at TermPositions or if you wanna extend some
kind of query have a look at Spans / SpanQuery
Anyway I have to admit I do not understand your example :)
