Range search in dependent collections
Hello,
I'm new to Lucene and I have the following problem:
I have a Users with first name, last name etc. and User Jobs (collection) with job title, start date, end date.
I need to perform search on all user fields (fist name, last name etc) and job fields (job title and optionally start date and end date).
What would be the best way to index and search this data?
Thank you,
Mykola Peleshchyshyn

Just repeat the first and last names in each document. How many users
and jobs are you talking about? Lucene will cope unless the numbers
are extremely large.
Note that I'm not claiming this is necessarily the "best" way, just
the simplest which is often, but not always, the best.

What about the case with several jobs? I.e.:
firstname: whatever
lastname: whatever
jobtitle1: somejob
startdate1: whenever
enddate1: whenever
.............................................
jobtitleN: somejob
startdateN: whenever
enddateN: whenever

Hi
The simplest way is to flatten your data into lucene documents that
hold all relevant info for user/job combinations. That will let you
search easily across whichever fields you want.
Your documents could look like this:
firstname: whatever
lastname: whatever
jobtitle: somejob
startdate: whenever
enddate: whenever
and searches could be something like lastname:whatever jobtitle:somejob.
