Beginner ? about exact match (i think)

i am a complete beginner here, but this is my issue:

an example of what we are considering a non-relevant search result is:
- if a user searches for the word "paint", we do not to return results
like "painter".

how do i exclude those type of matches from being returned?

Elasticsearch should take care of that already, try it on your local
machine first. In my example below, if you search for "car" you will not
get any results. If you search for "carp" however, you will get a result
back

curl -XPUT 'http://localhost:9200/animal/fish/1' -d '{"name" : "channel cat

fish", "type" : "cat-fish"}'
curl -XPUT 'http://localhost:9200/animal/fish/2' -d '{"name" : "blue cat
fish", "type" : "cat-fish"}'
curl -XPUT 'http://localhost:9200/animal/fish/3' -d '{"name" : "atlantic
salmon", "type" : "salmon"}'
curl -XPUT 'http://localhost:9200/animal/fish/4' -d '{"name" : "blue
salmon", "type" : "salmon"}'
curl -XPUT 'http://localhost:9200/animal/fish/5' -d '{"name" : "blue
carp", "type" : "carp"}'

curl -XGET 'http://localhost:9200/animal/fish/_search?pretty=true' -d
'{
"query" : {
"bool" : {
"should" : {
"match" : { "_all" : "carp"}
}
}
}
}'
