how index refresh rate happen in milvus

hi team
i have below doubts i checked the documentation still having few confusion

1. lets say i have built the index by 1k vectors. i passed query and got the results. now i have inserted another 100 records

during 100 records insertion, now the whole index will be rebuilt again using 1100 vectors or only this 100vectors are inserted to existing index.

2. while inserting , can we pass the query

3. in the first case, while the query is passed only 1000 record will considered or 1000 + (100 not inserted into index ) is considered

Milvus support two type of segments, growing and sealed.
When segment is not sealed/flushed, then you can insert into it.
Once it sealed, segment become immutable. New growing segment will be used to insert data.
when search happened we have to scatter gathering results from segment.
Background compaction happened to merge all the sealed segment to improve searvh
