PHP search optimization sphinx

Install. Environment: win7 64 bit

1. Download the sphinx file package

Download address: http://sphinxsearch.com/downloads/archive/

2. Unzip to D:/sphinx. Create new folders data and log, and import the example.sql file in the local test library. The structure is as follows

3. Configure and copy the sphinx.conf.in file to the bin directory. Rename to sphinx.conf. The configuration content is as follows. What each line means, I can't tell at the moment, let's follow up...

Note two points: the red is the content that I have modified, and the place with the yellow background needs to be named all the time.

# configure the data source
source src1
{
    type            = mysql
    sql_host        = localhsot
    sql_user        = root
    sql_pass        =
    sql_db          = test
    sql_port        = 3306    
    sql_query_pre    = SET NAMES utf8
    sql_query        = SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content \
        FROM documents
    sql_attr_uint        = group_id
    sql_attr_timestamp    = date_added
    sql_ranged_throttle    = 0
}

source src1throttled : src1
{
    sql_ranged_throttle    = 100
}

# Configure the location where the index files generated by the data source are stored
index test1
{
    source             = src1 
    path             = D:/sphinx/data/ test1 　　# Note that the generated file path and name are included here. A file in test1.*** format will be generated in the data directory 
   charset_table      = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U +430..U+44F, U+430..U+ 44F 
    docinfo             = extern 
    dict             = keywords
    mlock            = 0
    morphology        = none
    min_word_len    = 1
    ngram_len        = 1
    ngram_chars        = U+3000..U+2FA1F
    html_strip        = 0
}

{
    mem_limit        = 128M
}

# Configure Sphinx server information

    listen            = 9312
    listen            = 9306:mysql41
    log                = D:/sphinx/log/searchd.log
    query_log        = D:/sphinx/log/query.log
    read_timeout        = 5
    client_timeout        = 300
    max_children        = 30
    persistent_connections_limit    = 30
    pid_file            = D:/sphinx/log/searchd.pid
    preopen_indexes        = 1
    unlink_old            = 1
    mva_updates_pool    = 1M
    max_packet_size        = 8M
    max_filters            = 256
    max_filter_values    = 4096
    max_batch_queries    = 32
    workers                = threads 

　　# Start the searchd service under windows, be sure to comment out this 
 　　# seamless_rotate = 1

}

4. Create an index

indexer.exe test1

5. Start the service

searchd.exe --pidfile

6. If you need to close the service, close the DOC window directly

7, php installation sphinx extension not to mention. Add dll file under ext

Download address: http://pecl.php.net/package/sphinx

Configured under php.ini. restart apache

extension=php_sphinx.dll

This completes the configuration.

 

Test case 1. Output the ID that matches the search keyword

<?php

$keyword = 'test';
$sphinx = new SphinxClient;
$sphinx->setServer("localhost", 9312);
$sphinx ->setMatchMode(SPH_MATCH_ANY);    // The matching mode ANY is automatic word splitting for keywords, ALL is no word splitting matching (exact match) 
$sphinx->SetArrayResult ( true );     // The returned result set is an array 
$result = $sphinx->query($keyword, " test1 " );     // Asterisks are all index sources 
$count=$result[ ' total ' ];         // Number of results found 
$time=$result[ ' time ' ];             // Time-consuming 
$arr=$result[ ' matches ' ];         // Result set 
$id= '' ;
 for($i=0;$i<$count;$i++){
    $id.=$arr[$i]['id'].',';
}
$id =substr($id, 0 ,- 1 );             // The id string of the result set 

echo $id;

Results show:

 

Test case 2. Match search keywords highlighted

<?php


$keyword = 'test';
$sphinx = new SphinxClient();
$sphinx->SetServer('localhost',9312);
$sphinx ->setMatchMode(SPH_MATCH_ANY); // Match mode SPH_MATCH_ALL: exact match 
$result = $sphinx->query($keyword, ' * ' ); // * means search in all indexes 
$ids = implode( ' , ' ,array_keys($result[ ' matches ' ]));

$conn = mysqli_connect('localhost','root','');
mysqli_query($conn,'set names utf8');
mysqli_select_db($conn,'test');

$sql = "select * from documents where id in (".$ids.")";
$rst = mysqli_query($conn,$sql);
 // Add styles to matching keywords 
$opts = array(
     ' before_match ' => ' <font style="font-weight:bold;color:#f00;"> ' ,
     ' after_match ' => ' </font> '
);
echo '<pre>';
while($row = mysqli_fetch_assoc($rst)){
    $row2 = $sphinx->buildExcerpts($row, ' test1 ' ,$keyword,$opts); // Main data source index in test1 configuration file 
    print_r($row2);
}

 Results display
