If I've understood your question correctly, the answer is yes. Assuming the input data is coming from another file the flow will be along the lines of
. Open input file for reading . Open output file for writing . Open (or create) lucene index . For each input record - write to output file - add to lucene Then at the end close the files and the index and you're done. -- Ian.
