XF 2.2 Rebuild search index

Today i did a rebuild search index and noticed that my XF database grew from 1.8 Gb to 3.7 Gb right after the rebuild process finishes.
Any idea why this is happening?

How are you determining DB size? Many cases can just be estimates. Alternatively, InnoDB generally doesn't shrink its data files, so if there was once a large amount of data and it was subsequently deleted, that space would still be allocated.

Beyond that, the search index does take up a fair amount of space. If you didn't have much of an index before and you built the full index now, DB size growth would very much be expected.
