Hi,

after crawling, i have two webdb, i want to merge them and after merging i
created new WebDB (comibine both)
then i want searching on them.

i created new webdb under which i create two folder crawldb and segments
(which is combination of two webdb),
but now i want create Linkdb and index....
how this can be created......i use command like this in eclipse program
argument(Windows)

 invertlinks linkdb segments/*  
i got error like

INFO  crawl.LinkDb - LinkDb: starting
INFO  crawl.LinkDb - LinkDb: linkdb: invertlinks
INFO  crawl.LinkDb - LinkDb: adding segment: linkdb
INFO  crawl.LinkDb - LinkDb: adding segment: segments/*

LinkDb treats the parameter invertlinks as the path to linkdb (the 1st
parameter), remove it and the command should succeed.
