Whereas \fBsearchd\fR is responsible for searches in a server\-type environment, \fBsearch\fR is aimed at testing the index from the command line, and testing the index quickly without building a framework to make the connection to the server and process its response\&. .PP Note: \fBsearch\fR is not intended to be deployed as part of a client application; it is strongly recommended you do not write an interface to \fBsearch\fR instead of \fBsearchd\fR, and none of the bundled client APIs support this method\&. (In any event, \fBsearch\fR will reload files each time, whereas \fBsearchd\fR will cache them in memory for performance\&.) .PP That said, many types of query that you could build in the APIs could also be made with \fBsearch\fR, however for very complex searches it may be easier to construct them using a small script and the corresponding API\&. Additionally, some newer features may be available in the \fBsearchd\fR system that have not yet been brought into \fBsearch\fR\&. .PP When calling \fBsearch\fR, it is not necessary to have \fBsearchd\fR running; simply make sure that the account running the \fBsearch\fR program has read access to the configuration file and the index files\&. .PP The default behaviour is to apply a \fBsearch\fR for \fIword1\fR (AND \fIword2\fR AND \fIword3\fR\&.\&.\&. as specified) to all fields in all indexes as given in the configuration file\&. If constructing the equivalent in the API, this would be the equivalent to passing \fBSPH_MATCH_ALL\fR to \fBSetMatchMode\fR, and specifying * as the indexes to query as part of Query\&. .SH "OPTIONS" .PP There are many options available to \fBsearch\fR\&. .PP Firstly, the general options: .PP \fB\-\-config\fR\ \&\fICONFIGFILE\fR, \fB\-c\fR\ \&\fICONFIGFILE\fR .RS 4 Use the given file as its configuration, just as with \fBindexer\fR\&. .RE .PP \fB\-\-index\fR\ \&\fIINDEX\fR, \fB\-i\fR\ \&\fIINDEX\fR .RS 4 Limit searching to the specified index only; normally \fBsearch\fR would attempt to search all of the physical indexes listed in sphinx\&.conf, not any distributed ones\&. .RE .PP \fB\-\-stdin\fR .RS 4 Accept the query from the standard input, rather than the command line\&. This can be useful for testing purposes whereby you could feed input via pipes and from scripts .RE .PP Options for setting matches: .PP \fB\-\-any\fR, \fB\-a\fR .RS 4 Changes the matching mode to match any of the words as part of the query (word1 OR word2 OR word3)\&. In the API this would be equivalent to passing \fBSPH_MATCH_ANY\fR to \fBSetMatchMode\fR\&. .RE .PP \fB\-\-phrase\fR, \fB\-p\fR .RS 4 Changes the matching mode to match all of the words as part of the query, and do so in the phrase given (not including punctuation)\&. In the API this would be equivalent to passing \fBSPH_MATCH_PHRASE\fR to \fBSetMatchMode\fR\&. .RE .PP \fB\-\-boolean\fR, \fB\-b\fR .RS 4 Changes the matching mode to \fIBoolean matching\fR\&. Note if using Boolean syntax matching on the command line, you may need to escape the symbols (with a backslash) to avoid the shell/command line processor applying them, such as ampersands being escaped on a Unix/Linux system to avoid it forking to the \fBsearch\fR process, although this can be resolved by using \fB\-\-stdin\fR, as below\&. In the API this would be equivalent to passing \fBSPH_MATCH_BOOLEAN\fR to \fBSetMatchMode\fR\&. .RE .PP \fB\-\-ext\fR, \fB\-e\fR .RS 4 Changes the matching mode to \fIExtended matching\fR\&. In the API this would be equivalent to passing \fBSPH_MATCH_EXTENDED\fR to \fBSetMatchMode\fR, and it should be noted that use of this mode is being discouraged in favour of Extended2, below\&. .RE .PP \fB\-\-ext2\fR, \fB\-e2\fR .RS 4 Changes the matching mode to \fIExtended matching, version 2\fR\&. In the API this would be equivalent to passing \fBSPH_MATCH_EXTENDED2\fR to \fBSetMatchMode\fR, and it should be noted that use of this mode is being recommended in favour of Extended, due to being more efficient and providing other features\&. .RE .PP \fB\-\-filter\fR\ \&\fI\fR\fI\fR, \fB\-f\fR\ \&\fI\fR\fI\fR .RS 4 Filters the results such that only documents where the attribute given (attr) matches the value given (v)\&. For example, \fB\-\-filter\fR \fIdeleted\fR \fI0\fR only matches documents with an attribute called \*(Aqdeleted\*(Aq where its value is 0\&. You can also add multiple filters on the command line, by specifying multiple \fB\-\-filter\fR multiple times, however if you apply a second filter to an attribute it will override the first defined filter\&. .RE .PP Options for handling the results: .PP \fB\-\-limit\fR\ \&\fI\fR, \fB\-l\fR\ \&\fI\fR .RS 4 limits the total number of matches back to the number given\&. If a \*(Aqgroup\*(Aq is specified, this will be the number of grouped results\&. This defaults to 20 results if not specified (as do the APIs) .RE .PP \fB\-\-offset\fR\ \&\fI\fR, \fB\-o\fR\ \&\fI\fR .RS 4 offsets the result list by the number of places set by the count; this would be used for pagination through results, where if you have 20 results per \*(Aqpage\*(Aq, the second page would begin at offset 20, the third page at offset 40, etc\&. .RE .PP \fB\-\-group\fR\ \&\fI\fR, \fB\-g\fR\ \&\fI\fR .RS 4 specifies that results should be grouped together based on the attribute specified\&. Like the GROUP BY clause in SQL, it will combine all results where the attribute given matches, and returns a set of results where each returned result is the best from each group\&. Unless otherwise specified, this will be the best match on relevance\&. .RE .PP \fB\-\-groupsort\fR\ \&\fI\fR, \fB\-gs\fR\ \&\fI\fR .RS 4 instructs that when results are grouped with \fB\-\-group\fR, the expression given in \fI\fR shall determine the order of the groups\&. Note, this does not specify which is the best item within the group, only the order in which the groups themselves shall be returned\&. .RE .PP \fB\-\-sortby\fR\ \&\fI\fR, \fB\-s\fR\ \&\fI\fR .RS 4 specifies that results should be sorted in the order listed in \fI\fR\&. This allows you to specify the order you wish results to be presented in, ordering by different columns\&. For example, you could say \fB\-\-sortby\fR \fI"@weight DESC entrytime DESC"\fR to sort entries first by weight (or relevance) and where two or more entries have the same weight, to then sort by the time with the highest time (newest) first\&. You will usually need to put the items in quotes (\fB\-\-sortby\fR \fI"@weight DESC"\fR) or use commas (\fB\-\-sortby\fR \fI@weight,DESC\fR) to avoid the items being treated separately\&. Additionally, like the regular sorting modes, if \fB\-\-group\fR (grouping) is being used, this will state how to establish the best match within each group\&. .RE .PP \fB\-\-sortexpr\fR\ \&\fI\fR, \fB\-S\fR\ \&\fI\fR .RS 4 specifies that the search results should be presented in an order determined by an arithmetic expression, stated in expr\&. For example: \fB\-\-sortexpr\fR \fI"@weight + ( user_karma + ln(pageviews) )*0\&.1"\fR (again noting that this will have to be quoted to avoid the shell dealing with the asterisk)\&. Extended sort mode is discussed in more detail under the \fBSPH_SORT_EXTENDED\fR entry under the \fISorting modes\fR section of the manual\&. .RE .PP \fB\-\-sort=date\fR .RS 4 specifies that the results should be sorted by descending (i\&.e\&. most recent first) date\&. This requires that there is an attribute in the index that is set as a timestamp\&. .RE .PP \fB\-\-rsort=date\fR .RS 4 specifies that the results should be sorted by ascending (i\&.e\&. oldest first) date\&. This requires that there is an attribute in the index that is set as a timestamp\&. .RE .PP \fB\-\-sort=ts\fR .RS 4 specifies that the results should be sorted by timestamp in groups; it will return all of the documents whose timestamp is within the last hour, then sorted within that bracket for relevance\&. After, it would return the documents from the last day, sorted by relevance, then the last week and then the last month\&. It is discussed in more detail under the \fBSPH_SORT_TIME_SEGMENTS\fR entry under the \fISorting modes\fR section of the manual\&. .RE .PP Other options: .PP \fB\-\-noinfo\fR, \fB\-q\fR .RS 4 instructs \fBsearch\fR not to look\-up data in your SQL database\&. Specifically, for debugging with MySQL and \fBsearch\fR, you can provide it with a query to look up the full article based on the returned document ID\&. It is explained in more detail under the \fBsql_query_info\fR directive\&. .RE .SH "AUTHOR" .PP Andrey Aksenoff (shodan@sphinxsearch\&.com)\&.
