Controlling the search

 

In the center of the Agilent Literature Search display, there is a set of control panels which enable you to modify the parameters of the search.

 

The following controls are available to you for modifying the parameters of the search:

Search Controls

Max Engine Matches: sets the maximum number of "hits" per query string per search engine used.

 

Use Aliases: augment the query to include aliases for the terms in the "Terms" subpanel, using the species selected in the Concept Lexicon control.   If you have checked the Use Aliases control under Query Controls, then any aliases for a term (for the selected Concept Lexicon) will be incorporated into the query string.  Aliases are incorporated in a disjunctive (OR) manner: search engine(s) will look to match ANY of the aliases.

 

Use Context: toggle between using and not using Context in the search.  As you enter concepts into the Context panel, if you have  checked the Use Context control under Query Controls, then any concepts you have entered will be incorporated into the query string being built up in the Query Editor panel   Multiple lines of context words are incorporated in a disjunctive (OR) manner and are combined with Terms in a conjunctive (AND) manner.    Search engine(s) will look to match ANY of the context AND any term (or one of its aliases) in the query.

 

Concept Lexicon Limits Search: toggle between using and not using the name of the concept lexcicon as Context in the search.  This would be used if you wanted to restrict search results to a particular species.

Extraction Controls

Concept Lexicon: sets the concepts used for the search. This is for the purpose of creating aliases for terms of interest. It is also used in the extraction process, in determining the lexicon to be used when parsing and analyzing retrieved documents. Note that Concept Lexicon is used for aliasing and extraction, but it is not used by the search engines to restrict query results to concepts in that Concept Lexicon. In the current release, most of the concept lexicons are species related. In order to restrict queries to a particular species, you can add an organism name in the Context panel and this will result in the search engines constraining query results to that organism.

Interaction Lexicon: sets the level of stringency used by the Agilent Literature Search when generating putative interactions from sentences of interest.  Three options are specified in the current release: limited ; relaxed; or empty. Interaction Lexicon   is to be used when extracting "interesting sentences" from retrieved documents.
