I am using Sitecore 10.2 with SXA and I am using sitecore_sxa_web_index index. I have multiple articles which I am indexing. I am facing below issue:

1. Suppose I have 10 articles and when I manually do publish (republish) then in Solr it shows 10 articles.
2. When I do publish article as a Smart publish then it shows 3 article only.
3. When I rebuild indexes from control panel then it shows 3 articles only.

Below is my publishing strategy:

  <strategies hint="list:AddStrategy">
                            <strategy ref="contentSearch/indexConfigurations/indexUpdateStrategies/onPublishEndAsync" />
                        </strategies>
