Hi, Basically I need to index very large log files. I have modified the ExtractingDocumentLoader to create a new document for every 50 lines (it is made configurable by keeping it as a system property) of the log file being indexed. 'Filename' field for document created from 1 log file is kept the same and unique id is generated by appending the line no. with the file name, e.g 'log.txt (line no. 100 -150)'. Each doc is given the custom score stored in field called 'custom_score' which is directly proportional to its distance from the beginning of the file.
I have also found 'hitGrouped.vm' from the net. Since I am reading only 50 lines for each document so the default max chunk size works for me but it can be easily adjusted depending upon the no of lines you are reading per doc. Now I have done the grouping based on the 'filename' field and show the results from docs having highest score as a result I am able to show the last matching results from log file. Query parameters that I am using for search are: http://localhost:8080/solr/select?defType=dismax&qf=Content&q=Solr&fl=id,score&defType=dismax&bf=sub(1000,caprice_score)&group=true&group.field=FileName Results are amazing, I am able to index and search from very larger log files (few 100 MBs) with very low memory requirements. Highlighting is also working fine.

Thanks for your note, Anand. What was the maximum chunk size for you? Could you post the relevant portions of your configuration file? Thanks!
