Die Suchmaschine für die eigene Webseite

Mnogosearch ist eine Suchmaschine, die bei Hostsharing als Debian Paket installiert ist und für die eigene Webseite verwendet werden kann. Die bei HS installierte Version verwendet SQLite als Datenbank und ist für Webseiten bis einige tausend Seiten und Traffic, wie er auf einem Shared-Webserver vorkommt, gut geeignet.

Hier wird die Grundinstallation beschrieben. Mnogosearch ist eine sehr umfangreiche Software mit mannigfaltigen Konfigurationsmöglichkeiten. Für die weitergehende Konfiguration muß auf die Dokumentation von Mnogosearch verwiesen werden.

Installation

Für die Datenbank und die Konfigurationsdatei wird am besten pro Domain ein Verzeichnis "mnogosearch" eingerichtet und da die Konfigurationsdatei indexer.conf erstellt. Diese Datei kann auch von /etc/mnogosearch/indexer.conf kopiert werden und muss dann entsprechend geändert werden.

# cd /home/doms/example.com
# mkdir mnogosearch
# cd mnogosearch
# touch indexer.conf
# edit indexer.conf


Inhalt der Basis indexer.conf

Dies ist die stark gekürzte und auf das Notwendigste reduzierte Fassung. Ganz zu Beginn wird die Datenbankdatei und am Ende der zu indizierende Webserver definiert:

###########################################################################
# DBAddr <URL-style database description>
# Options (type, host, database name, port, user and password) 
# to connect to SQL database.
# Should be used before any other commands.
# Has global effect for whole config file.
# Format:
#DBAddr <DBType>:[//[DBUser[:DBPass]@]DBHost[:DBPort]]/DBName/[?dbmode=mode]

DBAddr sqlite://mnogo:@/home/doms/example.com/mnogosearch/mnogosearch.db/?dbmode=multi

# Default LocalCharset is iso-8859-1 (latin1).

# Full UNICODE
# LocalCharset UTF-8

###########################################################################
# StopwordFile <filename>
# Load stop words from the given text file. You may specify either absolute 
# file name or a name relative to mnoGoSearch /etc directory. You may use
# several StopwordFile commands.
#
StopwordFile stopwords/de.sl


#######################################################################
# HTTPHeader <header>
# You may add your desired headers in indexer HTTP request.
# You should not use "If-Modified-Since","Accept-Charset" headers,
# these headers are composed by indexer itself.
# "User-Agent: mnoGoSearch/version" is sent too, but you may override it.
# Command has global effect for all configuration file.
#
HTTPHeader "User-Agent: example.com-indexer"

# Section 2.
# URL control configuration.

# Allow Configuration
# Examples
#  Allow everything:
#Allow *
#  Allow everything but .php .cgi .pl extensions case insensitively using regex:
#Allow NoMatch Regex \.php$|\.cgi$|\.pl$
#  Allow .HTM extension case sensitively:
#Allow Case *.HTM

Allow *.html

##########################################################################
#Disallow [Match|NoMatch] [NoCase|Case] [String|Regex] <arg> [<arg> ... ]
#
# Examples:
# Disallow URLs that are not in udm.net domains using "string" match:
#Disallow NoMatch *.udm.net/*
# Disallow any except known extensions and directory index using "regex" match:
#Disallow NoMatch Regex \/$|\.htm$|\.html$|\.shtml$|\.phtml$|\.php$|\.txt$
# Exclude cgi-bin and non-parsed-headers using "string" match:
#Disallow */cgi-bin/* *.cgi */nph-*
# Exclude anything with '?' sign in URL. Note that '?' sign has a 
# special meaning in "string" match, so we have to use "regex" match here:
#Disallow Regex  \?


# Exclude some known extensions using fast "String" match:
Disallow *.b    *.sh   *.md5  *.rpm
Disallow *.arj  *.tar  *.zip  *.tgz  *.gz   *.z     *.bz2 
Disallow *.lha  *.lzh  *.rar  *.zoo  *.ha   *.tar.Z
Disallow *.gif  *.jpg  *.jpeg *.bmp  *.tiff *.tif   *.xpm  *.xbm *.pcx

Disallow *.pat  *.pm   *.m4   *.am   *.css
Disallow *.map  *.aif  *.sit  *.sea
Disallow *.m3u  *.qt

# Exclude Apache directory list in different sort order using "string" match:
Disallow *D=A *D=D *M=A *M=D *N=A *N=D *S=A *S=D

# More complicated case. RAR .r00-.r99, ARJ a00-a99 files 
# and UNIX shared libraries. We use "Regex" match type here:
Disallow Regex \.r[0-9][0-9]$ \.a[0-9][0-9]$ \.so\.[0-9]$

#AddType [String|Regex] [Case|NoCase] <mime type> <arg> [<arg>...]
# This command associates filename extensions (for services
# that don't automatically include them) with their mime types.
# Currently "file:" protocol uses these commands.
# Use optional first two parameter to choose comparison type.
# Default type is "String" "NoCase" (case sensitive string match with
# '?' and '*' wildcards for one and several characters correspondingly).
#
AddType image/x-xpixmap	*.xpm
AddType image/x-xbitmap	*.xbm
AddType image/gif	*.gif

AddType	text/plain			*.txt  *.pl *.js *.h *.c *.pm *.e

AddType text/rtf			*.rtf
AddType application/pdf			*.pdf
AddType application/msword		*.doc
AddType application/vnd.ms-excel	*.xls
AddType text/x-postscript		*.ps

# Default unknown type for other extensions:
AddType	application/unknown *.*


# Use ParserTimeOut to specify amount of time for parser execution
# to avoid possible indexer hang.

ParserTimeOut 300

# Document sections.
#
# Format is:
#
#   Section <string> <number> <maxlen> [clone] [sep] [{expr} {repl}]
#
# where <string> is a section name and <number> is section ID
# between 0 and 255. Use 0 if you don't want to index some of 
# these sections. It is better to use different sections IDs
# for different documents parts. In this case during search 
# time you'll be able to give different weight to each part
# or even disallow some sections at a search time.
# <maxlen> argument contains a maximum length of section
# which will be stored in database.
# "clone" is an optional parameter describing whether this
# section should affect clone detection. It can 
# be "DetectClone" or "cdon", or "NoDetectClone" or "cdoff".
# By default, url.* section values are not taken in account
# for clone detection, while any other sections take part
# in clone detection.
# "sep" is an optional argument to specify a separator between
# parts of the same section. It is a space character by default.
# "expr" and "repl" can be used to extract user defined sections,
# for example pieces of text between the given tags. "expr" is
# a regular expression, "repl" is a replacement with $1, $2, etc
# meta-characters designating matches "expr" matches.

# Standard HTML sections: body, title
