I am new to apache solr, and working on a package. The index created by solr has only .CFS, .gen, insegmentparents file, and .del file

Question

I know it contains header and file data in raw format, but does this mean everytime i query the index, the raw data is processed to find out the frequency of terms? Since I cannot see a .frq file? Is there any way to find out how the data is stored in .cfs file?

Answer 1

The Index file format is Compound and hence the cfs file created which has all the files combined.

Check File Format which will give a detail for Lucene Index file formats.

You can use Luke to explore your Lucene Index files.
