Why not use bloom filter in es for search?

as above. thanks

What benefits were you hoping to get by using bloom filters?

reduce space complexity

Please provide some more details. What benefit would it bring over the current approach?

I added a bloom filter into Lucene some years ago to try speed up primary key style look ups where there were many new keys being inserted. The benefits were negligible.

for example,if a filter match 1,000,000,000 documents, and with the help of bloom filter,es can catch them in the memory to get them quickly in case the same filter was executed again
