Vms is a view that joins : vm_static,vm_dynamic, vm_statistics
, vds_groups and storage_pool
those are not small tables , actually , this view may have millions of records 
as its result set. and even we are getting only the first page you will have to 
scan all to compute your regular expression

> In practice, I've tested the patch on env with more than 1000 data centers
and how many hosts & vms in each host did you have 
do a real test and turn the pg analysis on and you will see from the query plan 
what is the difference

BTW
1) what about other non-search queries returning results to the client , how 
does your patch addresses that ???
2) what about queries that fetch data from vdsm (for example getting the list 
of available images of an attached ISO domain) , how are you going to address 
that ???
3) Active directory / LDAP searches , how are you going to support that ???
