Question

I need to create phrase search using sphinx. I created my index using this config file

source sphinx_search
{
    type                                    = mysql
    # some straightforward parameters for SQL source types
    sql_host                                = localhost
    sql_user                                = root
    sql_pass                                = root
    sql_db                                  = mydatabase
    sql_port                                = 3306

    sql_query                       = \
        SELECT userId, usertype_id, searchdata from tbl_user;

    #sql_attr_uint                       = userId
    sql_attr_uint                       = usertype_id

     #document info query, ONLY for CLI search (ie. testing and debugging)
     #optional, default is empty
     #must contain $id macro and must fetch the document by that id
    sql_query_info      = SELECT * FROM tbl_user WHERE userId=$id;

}
index sphinx_search {
    source                          = sphinx_search
    path                            = /var/lib/sphinx/sphinx_search
    morphology                      = stem_en
    min_stemming_len        = 4
    stopwords                       = /var/data/sphinx/stopwords.txt
    min_word_len            = 3
    min_prefix_len          = 3
    min_infix_len           = 0
    enable_star                     = 1
    phrase_boundary = ., ?, !, U+2026 # horizontal ellipsis
    phrase_boundary_step = 100
    html_strip = 1

} 

indexer {
    mem_limit = 256M    
   #mem_limit       = 128M
    max_xmlpipe2_field = 16M 
}


searchd {   
    compat_sphinxql_magics  = 0     
    listen          = 9312  
    listen          = 9306:mysql41  
    log         = /var/log/sphinx/searchd.log   
    query_log       = /var/log/sphinx/query.log     
    read_timeout        = 5     
    max_children        = 30    
    pid_file        = /var/run/sphinx/searchd.pid   
    max_matches     = 10000     
    seamless_rotate     = 1     
    preopen_indexes     = 1     
    unlink_old      = 1     
    workers     = threads # for RT to work  
    binlog_path     = /var/data/ 
}

If I tried to search for “Water Pollution” word

The search result is showing like this

words:
1. 'water': 10554 documents, 37143 hits
2. 'pollut': 1902 documents, 9657 hits

First issue is its not taking that “pollution” word completely Instead of that its taking “pollut”.

Second problem is its not searching for that complete word. Even if I search

“water pollution”
like this.

third problem I am unable to sort my result with userId. If I tried to add

sql_attr_uint = userId

its not indexing properly.

Any body can help me to fix these issues. Please help me.

In a nutshell you have to set extended match mode and use extended query syntax:

$cl->SetMatchMode ( SPH_MATCH_EXTENDED );
$cl->Query ( '"Water pollution"' );

Notice double quotes around search term.
