Cannot import apache lucene
You'll now want to implement any required search functionality such as filtering by permissions, sorting by date, etc. Implement additional search functionalityīy now, you have a really basic search app which takes a query from the user and spits out a list of results. Do add some field boosts where you see fit to emphasize certain fields over others.ĥ. The searcher should accept a query string, and return a list of hits.Īfter you've implemented the most basic functionality, add functionality such as limiting the number of results displayed per page and moving between pages. Its always a good idea to separate the searching from the indexing. Write the searching code, in a separate class all the fields are there, all documents that should be indexed have been indexed, etc.Ĥ. When the first index has been created, browse the index using Luke, make sure it looks right, i.e. Start out simple, don't worry about efficiency or performance for now. Whether its files or a database that needs to be indexed, start by writing your indexer. Then, if your data is in a database for example, you would determine which database tables and columns need to be accessed, and what SQL select statements need to executed. Map your application to the Lucene modelįrom the search results page, determine what steps need to be taken to get your data into Lucene.įirst, determine what Fields there are in a Document. Pay attention to things like what data is to be displayed and how you'd like the results ranked.Ģ. The answer is simple: when you've figured out what search experience you're trying to produce, half the battle is won.

This might seem counter-intuitive - why at the end, not the beginning, like at the database?
