how can I use Solr to do real-time search

now we use deltaImport to update data from db to index. but we have some information 开发者_如何学Cneed a real-time search or near real-time search. what should I do if I use solr to solve this?

to generate near real-time-search i would update the data in small packages and also update the index in small packages every minute (index update needs only some seconds - depending on the size of new data)

don't forget to optimize the index regularly

You should take a look at Solr 3.3 with RankingAlgorithm 1.2. It supports NRT and can update 10,000 docs / sec. You can search concurrently during the updates. You can get more information from here:
