Lucene Newbie Questions
Hello all,
I'm considering Lucene for a specific application and am trying to ensure
that it is the right tool for what I'm trying to accomplish.
At a high level I have a list of restaurants in a database and a list of
tags related to the restaurant (e.g. Italian, Formal, Expensive, etc). Each
restaurant also has a location (longitude/latitude).
My primary goal using Lucene is to conduct searches where the user can do
things like:
- Misspell the name of the restaurant (by a few chars)
- Type "Italian Food" instead of just Italian or perhaps "Great Italian"
- Or even use some synonyms (e.g. Deli and Delicatessen) - of course I'd
define these terms.
Are these types of use cases something that can be done with Lucene? Or is
there a more appropriate API that I haven't found?
Thanks.

Based on your description, I would recommend Solr. It provides several
features such as spelling suggestion, faceting etc.
OOTB.
http://lucene.apache.org/solr/features.html
should answer all your questions.

>From a legal/technical perspective, you can either embed Solr or you can use it as a WebApp. I generally suggest that it be used as a separate WebApp, but that depends. I would suggest the following criteria:
1. Fitness to use cases
2. Effort to develop/adapt
3. Ease of deployment
4. Effort to upgrade/maintain
Solr does "for free" some of the things (like index reopening/Searcher-pattern) that you would have to handle in your application if you used Lucene. Depending on how much time you have and how much control you need, that may be a good or a bad thing.
You should be able to "try both" side-by-side in a few hours (the tutorials are pretty decent).

Thanks a bunch.
Since I'm already inside a java based web application it would seem like
both SOLR and Lucene would be plausible. I'm curious what other factors I
should know about in determing if SOLR or Lucene is right for me.
Can SOLR be used within a web application (as a library) or is it only a
standalone app.

Thanks a bunch.
Since I'm already inside a java based web application it would seem like
both SOLR and Lucene would be plausible. I'm curious what other factors I
should know about in determing if SOLR or Lucene is right for me.

Lucene can definitely do this stuff. This review of the Query Syntax might offer you some insight:
http://lucene.apache.org/java/2_4_0/queryparsersyntax.html
Specifically, you can look up "Fuzzy Searches" and "Synonyms". There are a couple of key ways to handle synonyms, so you might want to prototype that before you settle on the approach you ultimately select.
Be aware that Lucene is more of a "search library". If you're looking for a Web App. that can return XML or JSON, you might want to look into Solr, which uses Lucene, but offers a lot of the architecture you might need:
http://lucene.apache.org/solr/
Good luck!

You are certainly in the right place - Apache Solr (a search server
built using Lucene) provides what you are looking for out of the box.
