Hi all,
I have some specific requirements for highlighting. I need to search in
full content of item for phrase, and then show on which page searched
phrase is occuring. So i've created one field named text_content and fields
named text_content_{page_number} (text_content_1, text_content_2, etc.).
Example query is:
{
"highlight": {
"fields": {
"text_content_*": {}
}
},
"query": {
"match": {
"text_content": "lorem"
}
},
"size": 40
}
I've noticed that this query is fast, but only if i have small number of
documents in index. Quiering for documents is always fast (<40ms), but
highlight phase time is growing when number of documents in index is
growing.
I've stared thinking that highlighting may be processed before appending
"size": 40 - on the all matched documents. It's correct? How can in speed
up such case?
Regards,
Karol
