What are the side effects of using a large max_gram for an nGram tokenizer in elasticsearch? -

-

i want understand implications of using large setting max_gram when using ngram tokenizer. know explode size of index, what? make searches slower? cause things error out? etc

it'll make searches slower sure, because lots of tokens generated comparison.

in general, should analyze business , find out size of ngram suitable field. ex: product id, can support search ngram max 20 chars (max_gram=20), because people remember 5 or 6 chars of product id, 20 enough.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
