1. pgestraier - search Hyper Estraier indexes from PostgreSQL |
| 2 |
|
|
|
| 3 |
|
|
This package is essentially PostgreSQL C function which calls Hyper Estraier |
| 4 |
|
|
API and returns results in user defined format. |
| 5 |
|
|
|
| 6 |
|
|
2. Why is it written? |
| 7 |
|
|
|
| 8 |
|
|
Aside from providing single API to query your RDBMS and full text index |
| 9 |
|
|
(using any language that has PostgreSQL client libraries), real power is |
| 10 |
|
|
hidden in ability to join results from full text index and structured data |
| 11 |
|
|
in RDBMS. |
| 12 |
|
|
|
| 13 |
|
|
3. How to install |
| 14 |
|
|
|
| 15 |
|
|
Installation should be simple. However, you will have to have following |
| 16 |
|
|
software already installed before you try this function: |
| 17 |
|
|
|
| 18 |
|
|
* PostgreSQL (tested with version 7.4.8) with development libraries |
| 19 |
|
|
* Hyper Estraier (tested with versions 0.3.9 and 0.3.10) |
| 20 |
|
|
|
| 21 |
|
|
To run tests you will also need: |
| 22 |
|
|
|
| 23 |
|
|
* working perl installation |
| 24 |
|
|
* perl modules DBI, DBD::Pg, Test::More |
| 25 |
|
|
* trivia.list.gz from Internet Movie Database in data/ directory |
| 26 |
|
|
* database "test" with permissions for current user |
| 27 |
|
|
|
| 28 |
|
|
If you have all that, you should be able to type |
| 29 |
|
|
|
| 30 |
|
|
make |
| 31 |
|
|
|
| 32 |
|
|
and see sample results. You will be asked your password once (via sudo) to |
| 33 |
|
|
install pgest.so shared library in system-wide location so that PostgreSQL |
| 34 |
|
|
could access it. |
| 35 |
|
|

Next, you will have to create test index. You have two options: |
| 37 |
|
|
|
| 38 |
|
|
3.1. Create index using estcmd |
| 39 |
|
|
|
| 40 |
|
|
This will create temporary files on disk and index them using estcmd gather |
| 41 |
|
|
|
| 42 |
|
|
cd data |
| 43 |
|
|
make index |
| 44 |
|
|
cd .. |
| 45 |
|
|
|
| 46 |
|
|
3.2. Create index using Hyper Estraier perl bindings |
| 47 |
|
|
|
| 48 |
|
|
For this, you will have to install perl bindings from |
| 49 |
|
|
|
| 50 |
|
|
http://tokuhirom.dnsalias.org/~tokuhirom/archive/hyper_estraier_wrappers-0.0.6.tar.gz |
| 51 |
|
|
|
| 52 |
|
|
If you installed bindings as documented in README file, you can issue |
| 53 |
|
|
following commands to create index about three times faster than using |
| 54 |
|
|
estcmd: |
| 55 |
|
|
|
| 56 |
|
|
cd data |
| 57 |
|
|
make perl |
| 58 |
|
|
cd .. |
| 59 |
|
|
|
| 60 |

To run tests (which require that you have estcmd in your $PATH) issue |
| 61 |
|
|
|
| 62 |
|
|
make test |
| 63 |
|
|
|
| 64 |
|
|
See also included file test.sql for more examples of usage. |
