Programmers Stack Exchange is a question and answer site for professional programmers interested in conceptual questions about software development. It's 100% free, no registration required.

I have made a web application and now I would like to add a search option to it. Since it is a learning project, I can't afford to buy some Google license. That is why I consider creating my own search engine.

From what I have read, there are two major ways to do it: using Apache Lucene or using Apache Solr. I have read a bit about both, but I really don't understand what is the difference between them. Which one should I choose?

I am looking for something free which is easy to learn and use, so you have other suggestions please let me know.

Lucene is a search engine and Solr is a search application. With search engine you have to create everything from scratch, with search application you have everything out of the box.

Lucene is more shared-hosting friendly. You can create a basic search engine (without scoring, faceted search, etc) in an hour or two.

If your hosting provider allows you to install Solr, go for it. Otherwise Lucene should be just fine.

Solr is built on top of Lucene so everything you can do with Solr can be done with Lucene and few extra lines of code.

Thank you. I have no idea about how should I build that application. How long should it take until I will be able to search myapplication(where the results are links, like in every other search engine)? (I know that I a pushing it too far, but I really need an estimation in order to make a decision.) –  Dragos Mar 1 '12 at 10:46
    
I would recommend looking at Elastic Search, it's a decent replacement for Sorl. –  devmiles.com Mar 1 '12 at 12:43

Solr is the search platform which internally uses lucene API.

according to your requirement ,you may go for Solr

in 2010 both are merged.
