{"id":130988433,"name":"2011_04_24-1.m4v"}
{"id":130988434,"name":"2011_04_24-2.mp4"}
{"id":130988435,"name":"2011_04_24-3.mp4"}
index merging done [==============================================================] 67507 / 67507

search by number attributes/field

$ vfs-index search  -q='id == 130988433' --index=../idx --column=name --table=test --data=./
{"id":130988433,"name":"2011_04_24-1.m4v"}

$ vfs-index search -q='id == 130988471' --index=../idx --table=test --data=./
