Search in Sharepoint 2010 - New features

So it is time to have a look on search function that comes with sharepoint 2010.

With the sharepoint 2007 we had little work to get our search function done. (create a Search site, SSP configuration & crawling rule)

But now it is really simple.
It has additional functions that help user very much.

SEARCH(find_text,within_text,start_num)

Find_text is the text you want to find. You can use the wildcard characters — question mark (?) and asterisk (*) in find_text. A question mark matches any single character; an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.

Within_text is the text in which you want to search for find_text.

Start_num is the character number in within_text at which you want to start searching. Use start_num to skip a specified number of characters.
For example, suppose you are working with the text string "AYF0093.YoungMensApparel". To find the number of the first "Y" in the descriptive part of the text string, set start_num equal to 8 so that the serial-number portion of the text is not searched. SEARCH begins with character 8, finds find_text at the next character, and returns the number 9. SEARCH always returns the number of characters from the start of within_text, counting the characters you skip if start_num is greater than 1.



Special Points in Search of Sharepoint 2010

1. SEARCH does not distinguish between uppercase and lowercase letters when searching text.
2. SEARCH is similar to FIND except that FIND is case sensitive.
3. If find_text is not found, the #VALUE! error value is returned.
4. If start_num is omitted, it is assumed to be 1.
5. If start_num is not greater than 0 (zero) or is greater than the length of within_text, the #VALUE! error value is returned.


there are 3 types of search on SharePoint 2010
* Boolean Search
you can use AND, NOT and OR in your search queries. Be mindful though that you need to use capitals, otherwise they will considered additional search words.

* Wildcard Search
Search queries can now match a wildcard at the end of a text string.



* Faceted Search
When a search query returns a lot of results the faceted search functionality displays a refinement panel on the left side of the screen. In the panel you can refine the results based on criteria like Result type, Site, Author, Modified Date and Tags. What refinement possibilities are shown depends on the result set. Administrators can also configure other the categories that are used in the refinement panel based on managed properties and enterprise content management taxonomy nodes.


Finally we can add our portal as a "search connector to windows", that means it will search web url when we want to search a document :) :) :) :)
