I am clear with looping recursively to index all the file under Root folder. But the problem is if I want to search only in group1 or group2.Is that possible to search only in one of the group folder ? Cocula Remi <[EMAIL PROTECTED]> wrote: You just have to loop recurssively over the C:\tomcat\webapps\Root tree to create your index. Yes you can index databases; you will just have to write a mechanism that is able to create org.apache.lucene.document.Document from database. For instance : - connect JDBC - run a query for obtaining a ResultSet - loop for each row of that ResultSet : Create a new org.apache.lucene.document.Document from ResultSet data and add this document to the Index. end loop.
For incremental indexing, I suppose you have to store some timestamp field in your index; but it's up to you. Note that Lucene is very fast and I don't think that incremetal indexing is required for small or medium amout of data. -----Message d'origine----- De : mahaveer jain [mailto:[EMAIL PROTECTED] Envoy� : mardi 14 septembre 2004 17:22 � : [EMAIL PROTECTED] Objet : Help for text based indexing Hi I have implemented Text based search using lucene. I was wonderful playing around with it. Now I want to enchance the application. I have a Root folder, under that I have many other folder, that are group specific, say (group1, group2, .. so on). The Root folder is in C:\tomcat\webapps\Root and group folder within that. Now I am index for these groups separately, ie , I have index as C:/index/group1, C:/index/group2, C:/index/group3 and so on I want to know if I can have only one index for all these say C:/index/Root (this has index for all the folder) and I should be able to Search using C:\tomcat\webapps\Root\group1(if want to search for group1) similarly for the other groups. Let me know if this is possible and have anybody tried this. 2nd question Is lucene good to index databases ? How do we support incremental indexing ? (Right now I am using LIKE for searching ) Thanks in Advance Mahaveer --------------------------------- Do you Yahoo!? vote.yahoo.com - Register online to vote today! --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------- Do you Yahoo!? vote.yahoo.com - Register online to vote today!
