The next code snipped uses again the above Query method to create a RemoteQuery method. It allows to query any catalog on any remote machine available. It again hides the details of the connection string and how to modify the query string itself:. The method searches for the FROM clause in the query string and then replaces it with FROM followed by the remote machine name, a dot, the catalog name and two dots.

It uses a connection string without the data provider. Finally it again calls the Query method passing along the connection string and the modified query so that it can query the remote Indexing Server catalog. It only allows to query, it does not support any updates, inserts or deletes.

The supported query syntax is slightly adapted for this provider. You can find detailed documentation here. The biggest difference is in the FROM clause. The Indexing Server comes with the following pre-defined views. The referenced MSDN help page lists which fields are included in which view. This searches the paths specified and all the folders beneath it.

This actually is the default scope used when you only specify SCOPE , which means everything in the web site is included in the search. This searches the specified paths only, meaning it excludes any subfolder there might be. You can also include each command multiple times. Here are a few examples to look at:. This includes only the root and Help folder in the search.

None of the sub-folders are included. This example includes the Info and Help folders and all their sub-folders. Please refer to this article for a complete description. The LIKE operator can be used to perform pattern matching with wildcard characters. Here are a few examples:. This allows us to build some very complex queries utilizing the standard SQL language.

Building your own search engine which supports all this would be a major undertaking. We have seen so far how to set up Indexing Server to index files, folders and web sites.

What we have not yet covered is what types of content does Indexing Server search for you and how can you extend this. The Indexing Server extracts the content of files using the so called filters. Filters are components which implement the IFilter interface and do understand how to read the content of a file. Therefore there are different filters available for these different file types.

The following article lists which filter is able to read which file types. It also lists a number of additional available filters and from where you can download them. Keep in mind that the article talks about the MSN Desktop search, but all these filters apply to the Indexing Server also. You see for example a sub key called Catalogs which lists all the catalogs defined on this Indexing Server.

For each catalog you can also find all the settings. This also includes all the filters used by the Indexing Server. Comparing this with the article which lists all the available filters you can see out-of-the-box the following filters are installed:. These are all read as plain text files.

These are all files which contain or render HTML content. All these files are MS Office files. You can find a complete description of all the Indexing Server registry keys here. If you are interested to write your own filter for your custom file types, then follow this link. It provides a complete description of the IFilter interface you need to implement. Microsoft Indexing Server is a powerful indexing and search engine for your web or file search.

You can provide with no additional effort a simple text search as well as a powerful search with partial word, word and phrase matching. This includes stemming as well as language sensitive searching. This means there is no additional effort on your side, regardless of whether you index and search English or Asian content.

The filter framework provides the ability to extend the Indexing Server to search any custom content you might have. The attached sample application allows you to search any local or remote Indexing Server catalog.

You can enter the SQL query string to execute or select from a set of default query strings. The result-set is shown in a list view.

It also shows the number of returned matches. I want to hear if you have learned something new. Contact me if you have any questions about this topic or article.
