Hello - I am having a problem indexing and searching for words that may or
may not contain whitespace...Below is an example
Here is how the index is created:
curl -s -XPUT 'localhost:9200/test/name/1' -d '{ "street": "Lakeshore Dr" }'
curl -s -XPUT 'localhost:9200/test/name/2' -d '{ "street": "Sunnyshore Dr"
}'
curl -s -XPUT 'localhost:9200/test/name/3' -d '{ "street": "Lake View Dr" }'
curl -s -XPUT 'localhost:9200/test/name/4' -d '{ "street": "Shore Dr" }'
If I want to query for record 1/"Lakeshore Dr", I can using the following
query:
curl -s -XGET 'localhost:9200/test/name/_search?pretty=true' -d '{
"query":{
"bool":{
"must":[
{
"match":{
"street":{
"query":"lakeshore dr",
"type":"phrase"
}
}
}
]
}
}
}';
This returns the desired result of document id 1. But if a user searches
for "Lake Shore Dr" (a space between Lake and Shore), it is still desired
to return document id 1.
And the inverse of this problem is if a user searches for "Lakeview Dr"
(but indexed as "Lake View Dr"):
curl -s -XGET 'localhost:9200/test/name/_search?pretty=true' -d '{
"query":{
"bool":{
"must":[
{
"match":{
"street":{
"query":"lakeview dr",
"type":"phrase"
}
}
}
]
}
}
}';
The search matches to no documents. If the search is changed to a
booleansearch instead of a phrase
,
many docs will match on "dr", but doc #3, "Lake Shore" is not necessarily
returned as the top match.
NGrams at index time?? Ngrams at search time?? Remove whitespace at index
time/search time??
Any suggestions would be appreciated. Thanks.
