For implementation org.ametys.web.frontoffice.search.metamodel.impl.ResourceFormatSearchCriterionDefinition

It generates at query time (if selecting Text document for instance) :

(DCFormat:(application/msword))+OR+(DCFormat:(application/vnd.openxmlformats-officedocument.wordprocessingml.document))+OR+(DCFormat:(application/vnd.oasis.opendocument.text))+OR+(DCFormat:(application/rtf))+OR+(DCFormat:(text/rtf))+OR+(DCFormat:(application/x-abiword)) 

which is :

1. very annoying to read and understand for debug purposes
2. not optimized, generating a big OrQuery with many clauses is not optimal

We should create a new field, specific for the search service (i.e. for org.ametys.web.frontoffice.search.metamodel.impl.ResourceSearchable), and at index-time, it can only have the values:

• pdf
• image
• text
• pres
• spreadsheet
• video
• audio

Then at query time, the query will be more readable and more optimized
