67 |
|
|
68 |
|
=item C<debug> |
69 |
|
|
70 |
|
This option (off by default) will produce a lot of debugging output on |
71 |
|
C<STDERR> prefixed by C<##>. |
72 |
|
|
73 |
|
=item C<meta_in_body> |
74 |
|
|
75 |
|
This option (off by default) enables to search content of meta fields |
76 |
|
without specifying them (like they are in body of document). This will |
77 |
|
somewhat increase index size. |
78 |
|
|
79 |
|
=item C<use_stopwords> |
80 |
|
|
81 |
|
Use built-in SWISH++ stop words. By default, they are disabled. |

563 |
|
|
564 |
|
Currently there is no way to specify which meta data will be stored as |
565 |
|
properties. B<This will be fixed very soon>. |
566 |
|
|
567 |
|
There is no garbage collection on temporary files created for SWISH++. This |
568 |
|
means that one run of indexer will take additional disk space for temporary |
569 |
|
files, which will be removed at end. There should be some way to remove |
570 |
|
files after they are indexed by SWISH++. However, at this early stage of |
571 |
|
development it's just not supported yet. Have plenty of disk space! |
