Instance - UUID search

Purpose/Overview:
The purpose of this story is to provide an option for searching the instance record by Id only when the partial or the whole values are provided.

Requirements/Scope:
1. searches against Instance's id field (the field is string type, contains UUID value)
2. Id search supports following searches:

• "6506b79b*" search will return all instances that have id starting with "6506b79b"
• "6506b79b" search will not match any instance unless there is a record that matches exactly the phrase
• "6506b79b-7702-48b2-9774-a1c538fdd34e" returns only the instance with matching id
• "*7702-48b2-9774-a1c538fdd34e" search is supported (which will impact the performance)
• "*7702*" is not supported
• "6506b79b-*-48b2-9774-a1c538fdd34e" is supported (which will impact the performance)

Approach:

Acceptance criteria:

• Accurate record count provided
• If multiple results fulfill the search then the results are ranked based on term frequency, inverse document frequency and field length
• Supports search by entire value if no asterisks follows the query string. If asterisks is present partial matching should occur.
• The backend will not restrict the position of the asterisks within the search string even if this will have a impact on the search peformance

Out of scope:

• Autocomplete functionality - covered by MSEARCH-13
• Performance testing (suggested response under 5s for 10M records)
• UI implementation
