|
pgest-index.pl --create movies --sql "select id,title,year from movies" |

pgsql-index.pl --drop movies |

|
|
31 |
|
=item --create name |
32 |
|
|
33 |
|
Create index C<name> and create triggers on table with same name |
34 |
|
|
35 |
|
=item --drop name |
36 |
|
|
37 |
|
Remove triggers from table C<name> and node with same name |
38 |
|
|
39 |
|
=item --node-url http://localhost:1978/node/name |
40 |
|
|
41 |
|
Full URI to node. If it's not specified, it's assumed that you are using |
42 |
|
Hyper Estraier on C<http://localhost:1978/>. |
43 |
|
|
44 |
|
=item --sql "select col1,col2 from name" |
45 |
|
|
46 |
|
SQL query which will return names of columns which are included in full-text |
47 |
|
index. Have in mind that you can't use aliases (as I<something>) in this SQL |
48 |
|
query (or triggers will be created with wrong fields). |
49 |
|
|
50 |
|
If SQL query isn't specified, default one C<< select * from movies >> will |
51 |
|
be created. That will be B<serious performance hit> if all columns are |
52 |
|
not needed for search. |
53 |
|
|
54 |
|
=item --pk id |
55 |
|
|
56 |
|
Specify name of primary key column in SQL query. If you allready have primary |
57 |
|
key on table, and it consists of simgle column (compaund keys are not supported) |
58 |
|
it will be picked up automatically. |
59 |
|
|
60 |
|
If you specify value which is not unique, you will get just last occurence |
61 |
|
of that item in index (which might be what you want). That's because specified |
62 |
|
C<pk> column will be used for C<@uri> in Hyper Estraier. |
63 |
|
|
64 |
|
=item --user login |
65 |
|
|
66 |
|
=item --passwd password |
67 |
|
|
68 |
|
Username and password to use when connecting to Hyper Estraier. If not specified, |
69 |
|
C<admin> and C<admin> will be used. |
70 |
|
|
71 |
|
=item --debug |
72 |
|
|
73 |
|
Dump debugging output. It may be specified multiple times for more verbose |
74 |
|
debugging. |
