Procedure to integrate elastic search for Fuzzy search with any of the eGov modules.
Creating the index as per the requirement
The elastic index has to be used for fuzzy search due to performance enhancement and when PII fields are involved which cannot be accessed in DB directly to apply fuzzy logic.
When PII data are involved those fields shouldn’t be returned by the elastic search but only can be used to apply the filter. To enable this that particular field should be indexed but not stored.
eg -
{
"mappings": {
"general": {
"_source": {
"excludes": [
"name"
]
},
"properties": {
"id": {
"type": "text"
},
"dob": {
"type": "date"
},
"name": {
"type": "text"
}
}
}
}
}In the above example, when data is posted, all the fields will be stored, but the index will never return the excluded source fields when searched.
Querying an index
This is a simple request, there are that can be used to enhance the fuzzy search.
Elastic Integration with code
Add the elasticsearch host from the eGov cluster.
Divide the search params between the ones that will be sent to elastic and others to DB (search to elastic should be made only if the fuzzy fields are present in search request)
The result of the elastic search should be only the required primary-Id of the entity(property-id, trade license-id, etc..)
Then the resulting ids should be used in the normal search as it is.
Please refer to the following for the integration
Application Properties
Properties need to add for integration
The indices need to be reindexed for the fuzzy search to work if changes are done in the index. particularly in the case of protected fields being indexed but not to be returned in the search.
Reindexing for PT: .
#Elastic search properties
elasticsearch.host=http://localhost:9200/
elasticsearch.search.endpoint=/_search
property.es.index=property-services
pt.search.name.fuziness=2
pt.search.doorno.fuziness=2
pt.search.oldpropertyid.fuziness=2
pt.fuzzy.searh.is.wildcard=truecurl --location --request GET 'localhost:9200/_search?pretty' \
--header 'Content-Type: application/json' \
--data-raw '{
"query": {
"fuzzy": {
"name": {
"value": "ki"
}
}
}
}'curl -X GET "localhost:9200/_search?pretty" -H 'Content-Type: application/json' -d'
{
"query": {
"fuzzy": {
"name": {
"value": "ki",
"fuzziness": "AUTO",
"max_expansions": 50,
"prefix_length": 0,
"transpositions": true
}
}
}
}
'Step 1
Get the current mapping of the pt index using the _mapping API
GET /property-services/_mappingStep 2
Add the following json mappings in the existing mappings (parallel to properties key):
Sample QA final mapping for reference is attached at the end.
Step 3
Recreate property-services-enriched with the new mapping.
Step 4
Update the indexer configuration, add the following 3 fields ownerNames, doorNo, street in custom mapping as added below in sample configuration:
** If search has to be enabled only on names of only ACTIVE user, configure indexer jsonPath accordingly. Use $.owners[*][?(@.status=='ACTIVE')].name instead in the config
Step 5
Restart indexer
Step 6
Trigger reindexing
Recreated property-services-enriched index with the new mapping
Created kafka connector
Hit the legacy index api
Once data is indexed in property-services-enriched, verify that all the data is indexed
Sample mappings from QA env:
"_source": {
"excludes": [
"Data.street",
"Data.doorNo",
"Data.ownerNames"
]
}After validating the data, drop the property-services index and use alias to point property-services to property-services-enriched
POST /_aliases
{
"actions": [
{
"add": {
"index": "property-services-enriched",
"alias": "property-services"
}
}
]
}{
"mappings": {
"general": {
"_source": {
"excludes": [
"Data.street",
"Data.doorNo",
"Data.ownerNames"
