AEM - Search by content from text based document question

Hello All

I have two different documents (one.txt and two.txt) in same folder with same text. For example, 'Technical details page'

And Documents are re-indexed.

Backend search query is

fulltext = Technical details page

p.offset=0

p.limit=-1

type=dam:Asset

when searched for results. I'm getting only one document. One.txt

And when remove type=dam:Asset from above query. Many results are returned and has my two documents.

First Query Search Results

1. /content/dam/one.text

Second Query Search Results

1. /content/dam/one.txt

2. /content/dam/one.txt/jcr:content/renditions/page/jcr:content/par/text/text-16

3. /content/dam/two.txt

4. /content/dam/two.txt/jcr:content/renditions/page/jcr:content/par/text/text-10

The difference between first search results and second search (removed type=dam:Asset) results is that second query checked inside dam:Asset and returned my results.

Questions is: How the first query is able to return one.txt ? why did it not give two.txt in results?

How to fix this.?

Both docs have been indexed

Thanks,
