Maximum # of index-items?

In a genealogical document of over 1500 persons I try to make an alphabetical index of all the people in the document. But now, after I think 1000 index-items, it refuses to make more index-items. Is there a maximum?

HI Peter

There is no known limit of index elements. However, I guess, your index may have grown to a size that hits the limits of your hardware (memory, disk) and your computer stalls. Just a guess.

Last but not least, this forum is for documentation discussions. A better forum for support is available in our Ask forum at https://ask.libreoffice.org/c/english/5
