Index Build Threshold

[sugiyama_t]

[Background]

I have set scheduled runnig a batch file whcih indexes over 200,000 PDF files every weekend. However index creating has become failed since the week before last and not be able to create .idx files also.

The number of PDF files increases by about 100-200 during a each week, so that I suspect this problem is caused by excess of the max indexable number of PDF files.

This was because of "too much amount of PDF files".

Moving a large part of PDF files inside a target folder, I could make an index without any trouble.

Thanks for reading this question.
