If you exclude files from being indexed and then a few months later decide to include them, will they get processed?
To answer this question we first need to understand how Full Text Indexing works
Full Text Indexing process each file twice in the following manner.
So we can see that the extraction process ignores the settings for exclusions for the first pass and processes all files. But it adheres to the settings on the second pass and does not extract the data from files types that are excluded. The reason it does this, is as it processes the file the first time, if it is an “excluded” file, it flips a bit in the database for that file so that it does not try to process it on the second pass.
If the file type that was excluded has already had the first pass, then removing the exclusion will not automatically reset the bit for these files to be reprocessed. Once the file type has been removed from the exclusion list, a change will need to be made to the file in order to set the bit in the database to process the full text from the file. Here are a few ways to accomplish this:
*PLEASE NOTE* by remarking a folder for reprocessing, the process starts over where it has to run through both passes of the FTR process. We do not recommend remarking the entire datasource for reprocessing. If you have a large dataset, it will set you way behind in full text retrieval.
