C# Class SIL.FieldWorks.FDO.DomainServices.SemanticDomainSearch.SemDomSearchStrategy

Take a string to look in (from a domain's Name or ExampleWords) and try to find a match for some (strategy-defined) search key(s).

Each strategy defines how to determine whether a string has a match or not.

Get the text from a Semantic Domain's Name field. This version uses BestAnalysisAlternative which should always have a value, but a subclass might use a more specific writing system which may not have a value (i.e. be prepared for a null return value).

For one Semantic Domain question, return the text of the Example Words field. This baseclass version uses BestAnalysis, which always has a value, but a subclass might use a more specific writing system which could return a null value (i.e. be prepared to handle a null return value).

Takes a list of semantic domain question objects and fishes out the example words and puts them in a space-delimited string for easier searching. This version uses BestAnalysisAlternative.

Search through a list of words (results of Regex match) for a search key. Return a MatchingResult to inform caller of type of match, if any.

Constructor for new search strategy.

Subclasses can override to set the search results object to have the correct number of buckets for a different strategy. Baseclass defaults to two buckets.

Subclasses can override this method to change how Semantic Domains are compared with any search key(s) and the priority types of matches for putting the domain into an appropriate search results bucket (if any). N.B. Strategy subclasses should take care not to add a domain to a bucket if it is already in a higher priority bucket.
