I had this issue too. timeAllowed only works for a certain phase of the query. I think that's the 'process' part. However, if the query is taking time in 'prepare' phase (e.g. I think for wildcards to get all the possible combinations before running the query) it won't have any impact on that. You can debug your query and confirm that.
