Search API not invoked from fess search dashboard

when giving a search key on fess admin search page i am getting “The given query could not be processed” error and search not happening. Please let me know what is the root cause for this.

Please check the Fess log file (fess.log) for more details about the error.

I just find the below log in fess.log file
