We have developed a tag feature for the use of keywords in the query.
The tag feature allows you to refine your query by searching your keyword in one term.
Query : (Magnetic gear) equivalent to magnetic gear in one term !
Query : (Magnetic)(gear) equivalent to magnetic AND gear
Another possibility to master the tag feature is to use the advanced search, indeed its left side allows you to build a query composed of several keywords.
The "exact phrase" field means that the platform will search for keywords in documents in the form of a single character string, i.e. the keywords in one tag.
The "All keywords" field is equivalent to the use of an AND, one keyword per tag linked by default with an AND.
The "Any keywords" field is equivalent to the use of an OR, one keyword per tag linked by default with an OR.
The excluded field allows to eliminate from the results the documents containing the keyword.
By playing with the fields and switching from Advanced search to search. The user can learn to use the tag feature in the simple search.
The user enters "magnetic gear" keywords in the "All keywords" field of the advanced search.
Then he goes to the Search tab and the query is automatically completed with the tag way.
