Hello Elastic,
My dev team did a testing on the search terms for Elasticsearch on our apps site and the findings is that Elastic didn't highlight I would group it as preposition terms, such as 'the', 'with', are and etc.
Attached is the images where for example we search for terms "we are excited", however, the "are" terms did not highlighted.
Appreciate your guidance on this.
Thanks!
It's a question of analyzer. What is the mapping for this field ?
I'm not sure on the mapping part, but the way I ingest the data is through MSSQL Connectors.
They way you are collecting data (connectors, direct push, ETL...) does not influence the mapping.
What is your index name?
Check its settings in Kibana.
We have multiple fields involved and from what I observed, they have the same structure as below :
{
"type": "text",
"fields": {
"delimiter": {
"type": "text",
"index_options": "freqs",
"analyzer": "iq_text_delimiter"
}
Not sure if this is your asks, let me know if you require more info.
Thanks!
Could you share the full index settings (including the mapping)?
You can get this with:
GET /INDEXNAME

Which field is used when doing the search?
Actually could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.
A full reproduction script is something anyone can copy and paste in Kibana dev console, click on the run button to reproduce your use case. It will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.
Have a look at the Elastic Stack and Solutions Help · Forums and Slack | Elastic page. It contains also lot of useful information on how to ask for help.
Fields involved for search :
Below is our request script :
GET /search-portal/_search
{
"query": {
"bool": {
"must": [
{
"term": {
"dbo_post_isprivate": {
"value": "false"
}
}
},
{
"multi_match": {
"query": "we are a team",
"fields": ["dbo_post_title",
"dbo_post_title.stem",
"dbo_post_description",
"dbo_post_description.stem",
"dbo_post_files_in_post",
"dbo_post_files_in_post.stem",
"dbo_post_slug",
"dbo_post_slug.stem"]
}
},
{
"range": {
"dbo_post_publishdate": {
"gte": "2015-09-01T08:15:11.626015",
"lte": "2024-09-01T08:15:11.626015"
}
}
}
]
}
}
}
Could you complete the script so we can reproduce this locally and gives advices?
It needs a sample index to be created with sample data.
Note that it might not needed to reproduce on many fields but with one single field...
So the example is even easier to understand and build upon.
