search - Searching by name on ElasticSearch -


say have index thousands of names of clients , need able search them in administration panel, this:

john anders john smith sarah smith bjarne stroustrup

i want have full search capabilities on it, means that:

  1. if search john, should john anders , john smith.

  2. if search smith, should smith's couple.

  3. if search sarasmit or sara smit, should sarah smith searched initials of name , whitespace doesn't matter.

  4. if search johers or joh ers, should john anders searched strings contained in name.

i figured out use analyser lowercase filter , keyword tokenizer don't work every case.

what right combination of tokenizers/analysers/queries use?

have @ this, question asked regarding similar data set. here @ index settings/mapping have used produce decent results. development has ceased on interim i've produced far. can develop queries -
