are many live scenarios in sitecore application where we need to update the
index to reflect the changes on website (UI). As sitecore recommended we use
solr/lucence search index to play with huge data or search.
time we need to update some items or particular one item to update the index
here is the way to update the single item in index file:
tab: by default its hidden to show a developer tab, right-click a tab, and then
select the tab to show > developer.
> my toolbar >Customize>Add
Re-index Tree under indexing tools
which you want to rebuild the index
tree button > it will re build the index of selected item and its descendants.
Appreciate to some comments/suggestion
