Indexes with over 33%, sometimes even ~100% of the size of the original data

Hello,

We have observed in the past the indexes can get very large. Most people would probably expect the index to be 10% to maybe 30% of the total size of the original files. Unfortunately, we have observed values over 50% and you yourselves have observed that original files with a size of 466GB lead to an index of size 440GB (that’s over 94%) → RAM usage - #2 by yuriy.mazurchuk

Source corpus 986,262 files, 466 GB
Documents indexed 969,288
Extracted text 91.2 GB
Resulting index 440 GB across 740 segments
Machine 32 GB RAM
Outcome completed, no errors

I know that having a smaller alphabet and many stop words can reduce it a bit, but could you please find a general solution for a more efficient index storage?

Best regards
Jam
