Your WebForm & MVC search engine

We do not place a limit on the number of documents you can index.

There is no restriction on the number of search queries made by your users.

(Office 97 up, OOXML, ODF, PDF, RTF, TXT, HTML [aspx, html, asp, jsp...], ZIP, MSG)

By collecting and storing document data within an index, SearchUnit is able to retrieve information quickly and effectively.

Meet your client’s expectations and your user’s needs by utilizing our open API to implement the search solution you need.

The ASP.NET search engine has an optional Windows Service which can be installed for periodic rebuilds.

Flexible spelling control checks queries, and includes custom dictionary support for organization acronyms, jargon and names.

Documents within the search engine's index can be assigned to location categories and multiple content categories, giving users choice in which sections of the site are searched.

Includes User Control source code for total flexibility.

The search result summary is an extract of the original text showing as many of the search keywords as possible. Summary can include multiple extracts from various parts of the document when searched words are not close enough.

Word variations are (optionally) included in the search - in the example above the search term "downwards" yielded results with the same stem "downward" which were ranked lower (optional through an adjustable factor). Similarly a search for "downward" would yield results with "downwards", etc.

Brackets indicate grouping, "-" indicates a NOT operator, OR indicates OR logic, AND indicates AND logic (implicit when not specified). Groups can be nested to any number of levels, and may contain any legal expressions (phrases, NOT, OR, AND). Wildcards * can be used to indicate partial matches. Phrases as words surrounded by double quotes ".

Auto-complete displays suggestions as a user types a search term in the search box control.

Import and index rows from databases (MSSQL, Oracle, OLE) or any DataSet.

Automatic link discovery through the web site spider which reads and indexes pages ready for searching.

Document indexing by (optionally) recursive scanning of filesystem folders.

Quickly modify layout of search results through templates for; header, footer, no-results, result-item, error-message (for invalid search expressions).

Every customer has their own unique requirements and SearchUnit is flexible and extensible – usually offering multiple implementation options, thanks to its open API and plug-in architecture (all of which is pure .NET).

For example;

• maybe your application has a unique way of delivering documents to users, that you want to be searched.
• or maybe you want to filter out results based on your own logic.
• or index database records and other meta data but point the results to actual files, or BLOBs.

These are real world examples that we have helped customers with – let us know your situation and we’ll guide you through it.

Username and password combinations can be specified for multiple websites

Some search engines require the Microsoft Indexing Service to operate fully, however SearchUnit requires only .NET to be installed.

The SearchResult control optionally works with DataSet objects, which can contain results from any number of resources, such as;

• SQL database queries
• XML documents (see included example)
• Web service results
• Programmatically generated sets
• etc.
