I scan 1 URL Spider Mode, I scan another URL Spider Mode, and 1 scan Directory Offline Mode. How can I combine all of these in 1 search?
Are there any command line or any special techniques to getting this done.
There is no way just to combine sets of index files after indexing is finsihed.
There is also no way to index offline and online in the same session.
You can however index multiple online sites in a single session. So a solution might be to make the files that are currently available offline, available online. Of course you don't need to make the files available on the internet. Having them available via a web server on a local machine is enough. e.g. just install Apache on a local machine. Then you can index all the files in online mode.
Otherwise you could have two search boxes with two sets of index files. But I guess this is what you were trying to avoid.
