Adding the SearchPhaseResultsProcessor interface in Search Pipeline (opensearch-project#7283)

navneet1v · msfroh · andrross · shiv0408 · commit 3ba3f7efcc4f · 2024-04-25T19:56:58.000+05:30
* Initial code for adding the SearchPhaseInjectorProcessor interface in Search Pipeline

Signed-off-by: Navneet Verma &lt;navneev@amazon.com&gt;

* Pass PipelinedRequest to SearchAsyncActions

We should resolve a search pipeline once at the start of a search
request and then propagate that pipeline through the async actions.

When completing a search phase, we will then use that pipeline to inject
behavior (if applicable).

Signed-off-by: Michael Froh &lt;froh@amazon.com&gt;

* Renamed SearchPhaseInjectorProcessor to SearchPhaseResultsProcessor and fixed the comments

Signed-off-by: Navneet Verma &lt;navneev@amazon.com&gt;

* Make PipelinedSearchRequest extend SearchRequest

Rather than wrapping a SearchRequest in a PipelinedSearchRequest,
changes are less intrusive if we say that a PipelinedSearchRequest
"is a" SearchRequest.

Signed-off-by: Michael Froh &lt;froh@amazon.com&gt;

* Revert code change from merge conflict

Signed-off-by: Michael Froh &lt;froh@amazon.com&gt;

* Updated the changelog with more appropiate wording for the change.

Signed-off-by: Navneet Verma &lt;navneev@amazon.com&gt;

* Fixed Typos in the code

Signed-off-by: Navneet Verma &lt;navneev@amazon.com&gt;

* Fixing comments relating to return of SearchPhaseResults from processor

Signed-off-by: Navneet Verma &lt;navneev@amazon.com&gt;

* Moved SearchPhaseName enum in separate class and fixed comments.

Signed-off-by: Navneet Verma &lt;navneev@amazon.com&gt;

* Resolve remaining merge conflict
