Of special interest maybe are the -i and -f options. -i allows indexing an
|
|
|
544 |
explicit list of files (given as command line parameters or read on
|
|
|
545 |
stdin). -f tells recollindex to ignore file selection parameters from the
|
|
|
546 |
configuration. Together, these options allow building a custom file

recollindex -i will not descend into directory parameters, but just add
|
|
|
552 |
them as index entries. It is up to the external file selection method to
|
|
|
553 |
build the complete file list.
