Concepts and Capabilities

10 |SharePoint Saturday Atlanta

Importance of Search Content Aggregation and Portability

Becoming the defacto technique Easy to access Security Trimming

Allows you to quickly and securely render dynamic content from any source/site in the index


Advantages of FAST System Advantages

Extreme scalability of the search sub-system

Advanced crawling and ranking algorithms

Relevancy customizations

Query Advantages More complex queries Advanced sorting and

ranking options Advanced refinement

options


Customization Ideas Dynamic Content Based On User’s

Audience/Properties News Rollups Dynamic Site Directory Related Content


Object Model Overview


FAST versus SharePoint Search FAST Query Modes:

Keyword Queries and FQL

FullTextSQLQueries not supported

Advanced Sorting and Ranking SortByProperties

property

Find Similar Results FindSimilar property

Advanced Refinement IncludeRefinementResult

s and RefinementFilters properties


Enterprise Search APIs Microsoft.Office.Server.Search is the core

namespace for both SharePoint Server Search and FAST for SharePoint

KeywordQuery mQuery = new KeywordQuery(searchProxy); mQuery.EnableFQL = true;mQuery.QueryText = “body:Contoso”;mQuery.ResultTypes = ResultType.RelevantResults;ResultTableCollection resultsTableCollection; resultsTableCollection = mQuery.Execute();


People Search People Search is not performed by FAST,

but delegated to FAST Query SSA

Set the ResultsProvider property to SharePointSearch

mQuery.ResultsProvider = SearchProvider.SharepointSearch;


Intro to FAST Query Lang


FQL Overview Definition - Query Language used to perform

precise searches and refinements on indexed content.

The length of FQL queries is limited to 2,048 characters.

Create simple or complex expressions that can identify and narrow relevant results. Token expressions - One or more query terms,

phrases, or numeric values to search for in a query Property specification - A property or full-text index

to match with the expression value Operators - Keywords that specify Boolean operators

(such as AND, OR) or other constraints to operands (such as FILTER OR RANK)


Token Expressions Wildcard

Expressions The * is for 0 or more

characters The ? Is for 1 character

Examples Text* *text *text* Te?t *te?t

Numeric Expressions Int Float Date & Time Expressions

YYYY-MM-DD YYYY-MM-DDThh:mm:ss YYYY-MM-DDThh:mm:ssz


Property Specification Important - Properties must be in

lowercase characters regardless of how it is specified

Examples: title:and(much, nothing) and(title:much, title:nothing) title:string("much nothing", mode="and")


Property Specification, cont. The following FQL query example searches

for the terms “pharmaceutical" and “testing" in the category managed property of an indexed item:

category:string(“pharmaceutical testing", mode="and") In the example:

category: limits the scope of the query to the category managed property within the item.

"pharmaceutical testing" is the operand to the STRING operator, which indicates the terms to search for.

mode="and" indicates that the logical query operator AND will be applied to "pharmaceutical testing".


Operators Logical

And, +, Or, Any Andnot, Not, - Equals Starts-with Ends-with Max Min Range

Datatypes Int, Int32, Int64 Float, Double Datetime

Search Count Rank Xrank Scope Phrase

Recommended Next Steps Experiment with FQL development Consider using FQL for any new

customizations Start porting existing customizations to

FQL
