假定 MySQL 正在运行,使用如下所示的代码运行索引器来创建索引。
清单 10. 创建索引
| $ sudo /usr/local/bin/indexer --config /usr/local/etc/sphinx.conf --all Sphinx 0.9.7 Copyright (c) 2001-2007, Andrew Aksyonoff using config file '/usr/local/etc/sphinx.conf'... indexing index 'catalog'... collected 8 docs, 0.0 MB sorted 0.0 Mhits, 82.8% done total 8 docs, 149 bytes total 0.010 sec, 14900.00 bytes/sec, 800.00 docs/sec |
注: -all 参数将重构 sphinx.conf 中列出的所有索引。如果不需要重构所有索引,您可以使用其他参数只对部分索引进行重构。
您现在可以使用如下所示的代码用 search 实用程序测试索引(不必运行 searchd 即可使用 search)。
清单 11. 用 search 测试索引
| $ /usr/local/bin/search --config /usr/local/etc/sphinx.conf ENG Sphinx 0.9.7 Copyright (c) 2001-2007, Andrew Aksyonoff index 'catalog': query 'ENG ': returned 2 matches of 2 total in 0.000 sec displaying matches: 1. document=8, weight=1, assembly=5, model=7 id=8 partno=ENG088 description=Cylinder head price=55 2. document=9, weight=1, assembly=5, model=3 id=9 partno=ENG976 description=Large cylinder head price=65 words: 1. 'eng': 2 documents, 2 hits $ /usr/local/bin/search --config /usr/local/etc/sphinx.conf wind Sphinx 0.9.7 Copyright (c) 2001-2007, Andrew Aksyonoff index 'catalog': query 'wind ': returned 2 matches of 2 total in 0.000 sec displaying matches: 1. document=1, weight=1, assembly=3, model=1 id=1 partno=WIN408 description=Portal window price=423 2. document=5, weight=1, assembly=3, model=1 id=5 partno=WIN958 description=Windshield, front price=500 words: 1. 'wind': 2 documents, 2 hits $ /usr/local/bin/search \ --config /usr/local/etc/sphinx.conf --filter model 3 ENG Sphinx 0.9.7 Copyright (c) 2001-2007, Andrew Aksyonoff index 'catalog': query 'ENG ': returned 1 matches of 1 total in 0.000 sec displaying matches: 1. document=9, weight=1, assembly=5, model=3 id=9 partno=ENG976 description=Large cylinder head price=65 words: 1. 'eng': 2 documents, 2 hits |
第一条命令 /usr/local/bin/search --config /usr/local/etc/sphinx.conf ENG 在零件号中找到了两个含有 ENG 的结果。第二条命令 /usr/local/bin/search --config /usr/local/etc/sphinx.conf wind 在两个零件描述中找到了子字符串 wind。而第三条命令把结果限定为 model 为 3 的条目。
编写代码
最后,您可以编写 PHP 代码来调用 Sphinx 搜索引擎。Sphinx PHP API 非常小并且易于掌握。清单 12 是一个小型 PHP 应用程序,用于调用 searchd 以得到使用上面所示的最后一条命令得到的相同结果(“在属于型号 3 的名称中找到含有 ‘cylinder’ 的所有零件”)。
清单 12. 从 PHP 调用 Sphinx 搜索引擎
| <?php include('sphinx-0.9.7/api/sphinxapi.php'); $cl = new SphinxClient(); $cl->SetServer( "localhost", 3312 ); $cl->SetMatchMode( SPH_MATCH_ANY ); $cl->SetFilter( 'model', array( 3 ) ); $result = $cl->Query( 'cylinder', 'catalog' ); if ( $result === false ) { echo "Query failed: " . $cl->GetLastError() . ".\n"; } else { if ( $cl->GetLastWarning() ) { echo "WARNING: " . $cl->GetLastWarning() . ""; } if ( ! empty($result["matches"]) ) { foreach ( $result["matches"] as $doc => $docinfo ) { echo "$doc\n"; } print_r( $result ); } } exit; ?> |
要测试代码,需要为 Sphinx 创建 log 目录,启动 searchd,然后运行 PHP 应用程序,如下所示:
清单 13. PHP 应用程序
| $ sudo mkdir -p /var/log/searchd $ sudo /usr/local/bin/searchd --config /usr/local/etc/sphinx.conf $ php search.php 9 Array ( [fields] => Array ( [0] => partno [1] => description ) [attrs] => Array( [assembly] => 1 [model] => 1 ) [matches] => Array( [9] => Array( [weight] => 1 [attrs] => Array( [assembly] => 5 [model] => 3 ) ) ) [total] => 1 [total_found] => 1 [time] => 0.000 [words] => Array( [cylind] => Array( [docs] => 2 [hits] => 2 ) ) ) |
