mnoGoSearch^tm (former UDMSearch) web search engine software

General information

mnoGoSearch (formerly known as UdmSearch) is a full-featured web search engine software for intranet and internet servers.

mnoGoSearch software has a number of unique features (please see below), which makes it appropriate for a wide range of applications from search within your site to specialized search systems such as cooking recipes or newspaper searches, ftp archive search, MP3 search, news articles search or even national-wide portal search engine.

Our search software consists of two parts. The first is an indexing mechanism (indexer). The purpose of the indexer is to walk through HTTP, FTP, NEWS servers or local files, recursively grabbing all the documents and storing words meta-data about those documents in an SQL database in a smart and efficient manner.

After every document is referenced by its corresponding URL, meta-data, collected by the indexer is used later in the search process. The search is performed via Web interface. C CGI front end, PHP search script and Perl search script are included

Features

mnoGoSearch (formerly known as UdmSearch) has number of unique features, which make it capable of wide range of application - from search within your site to a specialized search system.

• Full text indexing. Different priority can be configured for body, title, keywords, description of a document.
• Supporting all widely used single- and multi-byte character sets, including UTF8, as well as most of the popular Eastern Asia languages.
• Automatic document character set and language guesser for about 70 charset/language combinations.
• ASP-frontend
• Web-configurator
• HTTP/1.0 support
• FTP support
• NNTP support (both news:// and nntp:// URL schemes) in standard and extended modes.
• HTTP Proxy support
• Local file system indexing support (file: URL schema)
• Supporting gzip, deflate, compress content encoding
• Built-in database support
• Different SQL databases support. Currently MySQL, PostgreSQL, miniSQL, Solid, Virtuoso, InterBase, Oracle, SyBase, MS SQL, iODBC, unixODBC, EasySoft ODBC-ODBC bridge IBM DB2 Caché databases may be used as mnoGoSearch backend.
• Search clusters: a possibility to distribute database between several machines.
• Basic authorization support (to index password protected areas)
• Both HTML documents and plain text files can be indexed
• External parsers support for other file types (pdf, ps, doc etc.)
• Mirroring features
• Stopwords support
• "keywords" and "description" META tags support
• User defined META tag support.
• Reentry capability. You can run few indexers and searching processes at the time
• Continual indexing
• Indexing depth can be limited
• Robots exclusion standard support (both <META NAME="robots"> and robots.txt)
• HTML templates to easily customize search results

• Fuzzy search: different word forms, synonyms, substrings
• C CGI, PHP3, Perl search frontends
• Search on subsection of database
• It is very flexible. You can configure mnoGoSearch to run in different modes, including 'ftpsearch mode' (searching through URLs rather than their content),'link validation' (to check site for bad references), 'netminder' (What's new since ...?). There is also extended news support built into the package

Frequently Asked Questions

How can I contribute to the project?

There are several ways you can help.

What are the differences between versions of mnoGoSearch for Windows ?

mnoGoSearch for Windows is available in three different versions. Choose the version that suits you best!

The differences between versions Lite and Pro:

mnoGoSearch Lite version is designed to work with small volumes of data (1000-3000 documents) and features a built-in database, so that no additional database software is needed. This version does not have SQL servers support.

mnoGoSearch PRO version is designed to handle large amount of data. It works through ODBC and has been tested with MS SQL Server, MySQL, InterBase, PostgreSQL, SyBase, OpenLink Virtuoso, DB2, using corresponding ODBC drivers. This version also features NT Service for scheduling indexations and remote administration. mnoGoSearch Pro is designed for Windows NT/2000/XP only and will not run on Windows 9x.

Regarding mnoGoSearch for Windows: When I'm trying to search, it says that search.htm is included. However, after I run the install, there is no search.htm anywhere to be found. I have indexed my site, but can't search it, because there is not search.htm included.

You should create a new template from the Wizard:
press "Wizard" button at the toolbar, on the "Search template" step press "Create new" then "Adjust" buttons

If I have pages with no keywords in the META description, will the document get indexed?

Yes. By default mnoGoSearch does index whole document. By changing the default values you can give different weights to different parts of the document: body, title, keywords, description.

When searching words in spanish (accentuated characters) with search.cgi I get results like the following: If I search for "España", search.cgi breaks the word in two parts, searching for "Espa" and also for "a", ignoring "ñ".

Have you set local charset to 8859-1? If not, do so in both indexer.conf and search.htm .

I'm wondering if mnoGoSearch supports multi-byte char code sets. I'm especially interested in EUC-JP.

mnoGoSearch-3.2+ has multibyte support, 3.1..x or earlier has no such features.

Why indexer fails with the message like indexer: can't load library 'libmysqlclient.so.6'?

You probably don't have MySQL libraries properly installed. On Linux just find out where is your libmysqlclient.so.6 and enter the path to that file to /etc/ld.so.conf. Then run ldconfig as root.

You can as well set up the value of environment variable LD_LIBRARY_PATH with the path to required dynamic libraries. This works on any OS.

Note that this is a general UNIX configuration issue, not only mnoGoSearch specific.

What is the maximum size of server(s) mnoGoSearch can run with?

Cache storage mode, introduced in 3.1.x, is able to index and search through several millions documents.

I want to index multiple virtual domains on a single box. What settings do I need to change for that?

It is fully supported. No special settings are required.

Is it possible to use different templates for searches, i.e. view search results in the design of different sites without having to recompile search.cgi?

There are actually several ways to do it. They are given here in the order how search.cgi detects template name.

• search.cgi checks environment variable UDMSEARCH_TEMPLATE. Thus you can enter a path to desired search template into this variable.
• search.cgi also supports Apache internal redirect. It checks REDIRECT_STATUS and REDIRECT_URL environment variables. To activate this template option you may add these lines to Apache srm.conf:

  AddType text/html .zhtml
  AddHandler zhtml .zhtml
  Action zhtml /cgi-bin/search.cgi
  

  Put search.cgi into your /cgi-bin/ directory. Then put HTML template into your site directory structure under any name with .zhtml extension, for example template.zhtml. Now you may open search page: http://www.site.com/path/to/template.zhtml Of course you may use any available extension instead of .zhtml.

• If the above two ways fail, search.cgi will open a template which has the same name with the script being executed using SCRIPT_NAME environment variable. search.cgi will open a template ETC/search.htm, search1.cgi will open ETC/search1.htm and so on, where ETC is mnoGoSearch /etc directory (usually /usr/local/mnogosearch/etc). So, you can use the same search.cgi with different templates without having to recompile it. Just create one or several hard or symbolic links for search.cgi or copy it under different names then put correspondent search templates into /etc directory of mnoGoSearch installation.

  The libtool I get in my current directory gives a bad test. If I put "/usr/bin/libtool" in the Makefile and src/Makefile instead, everything is ok.

  You have a new virsion of libtool in your system. Please, run bootstrap script.
