Just a note about merging. In 2.0, you can only merge in pairs:
-M file1 file2 mergedfile
The following does not work:
-M file1 file2 ... filen mergedfile
So, to do that
-M file1 file2 mergedfile1
-M mergedfile1file3 mergedfile2
-M mergedfilem filen mergedfile
Sorry for the inconvenience. Because merging files is entirely made
in RAM, this approach uses less memory.
The phrase search introduced in 2.0 makes swish use more RAM (to
store word's positions) when index and merging. So merging more
than two files at once can make some machines run out of memory
or, at least, page a lot.
