Lucene Searches involving the dash (-) character

Hello,

very likely this is the result of tokenisation during indexing and searching. The dash character is a natural place to perform tokenisation. Since the tokens "RFT", "TS" and "16" are contained in the result it is returned - even if you have the token "16" twice in your search. To look for exact matches, the query should likely use =@cm:name:"RFT-TS-16-16". I strongly advise to NOT use legacy luceneSearch anymore and instead opt for query() with search language fts-alfresco. The lucene language has various drawbacks, especially that it doesn't support the "transactional metadata query" feature added in 4.2.

Thanks so much for the quick response and suggestions. I'm now using search.query with fts-alfresco and it's working perfectly with wildcards:

var searchObj = {
query: 'PATH:"/app:company_home/st:sites/cm:grey-county/cm:documentLibrary//*" AND @cm\:name:"*RFT-TS-16-16*"',
language: 'fts-alfresco'
}

var results = search.query(searchObj);
