can't use * in saved object searches

[bhavyarm]

Kibana version: master

Browser version: chrome latest

Browser OS version: os x

Original install method (e.g. download page, yum, from source, etc.): from snapshots

Describe the bug: Search isn't working on search bar on the new saved objects page.

[jen-huang]

Replicated bug - this only happens when * is present in the query. logstash searches fine. Removing blocker label since * can just be omitted (redundant as all queries are partial match already).

[jen-huang]

Further investigation - search behavior is inconsistent. Might be a combination of the search bar parsing and saved objects find api.

[jen-huang]

Two fold issue:

• EuiSearchBar errors out on certain characters, causing logstash-* to never be queried, EUI bug opened Can't use _ or * in EuiSearchBar eui#951
• Saved objects _find endpoint doesn't retrieve partial matches for all queries. For example, logstash and dashboard returns results, but not stash and board:

Search on the new UI has more problems. I am marking this bug as regression. It breaks functionality for users:

Here are some sample search terms and their queries in 6.3.2 and 6.4.0:

1. saved_object
   6.3.2: Request URL: https://xxxxx/api/saved_objects/_find?type=dashboard&search=saved_object*&per_page=100&page=1&search_fields=title%5E3&search_fields=description
   6.4.0: https://localhost:5601/api/saved_objects/_find?per_page=50&page=1&sort_field=type&fields=title&fields=id&search_fields=title&type=index-pattern&type=visualization&type=dashboard&type=search

2. saved object
   6.3.2: Request URL: https://xxxxx/api/saved_objects/_find?type=dashboard&search=saved*&per_page=100&page=1&search_fields=title%5E3&search_fields=description

6.4.0: https://localhost:5601/api/saved_objects/_find?search=saved%20object*&per_page=20&page=1&sort_field=type&fields=title&fields=id&search_fields=title&type=index-pattern&type=visualization&type=dashboard&type=search

@jen-huang @bhavyarm was this issue fixed as part of EUI conversion?

[jen-huang]

@rayafratkina No, this was found after EUI conversion so is still outstanding.

on 6.6.0 searches work on both partial and full terms "ngi" and "nginx" both find saved objects containing nginx.
But any search containing * returns no results. Is that a regression? From when? It's the same in 6.4.2.
Searching on the Discover saved searches, or Visualization landing page, or Dashboard landing page with * also shows no results. So it's all consistent for the last couple of major releases.

In light of that, I think we should update the description to can't use * in saved object searches.

@epixa @LeeDr should we treat this as a blocker for 6.7?

[epixa]

@jinmu03 This has been in the wild for a little while, so I don't think blocking a new release will help anything.

Similar to #5734 and will be solved at the same time. Please refer to it.
