Search Results to show text context

It seems that version 19 of Edocman search allows the search result window to show some text around the searched text.
How do we turn that feature on?

Hi John,
Yes, that feature is available on Joomla Search plugin of Edocman already.
Thanks

That is good to hear. However, I cannot figure out how to turn this feature on. My search results only give the title, category, size and date.
Do I need to change a template or is there a selection in the Extensions=> Modules=> EDocman search pages? If so which tab?

Hi John,
As i mentioned you in my previous post, it's Joomla Search plugin, so that, you should
1. Enable Joomla Search module or setting up menu to Joomla Search layout.
2. Enable Joomla Search plugin: Edocman Search
Thanks

Maybe I am not being clear. Yes, I have the Edocman Search plugin working. My question is about the layout of the results. I can get 3 layouts which you can see in the attachment. They give very little information except for the filename where the search term is located. Note, there is no text to show where the search term is located in a paragraph.

In my "other" attachment, you can see that Google and the standard Joomla search both show both the search term and a few words around the search term in the Search Results screen. It is those words that I am looking for.

Hi,
3 first pictures are Documents layouts of Edocman, they are: Default, Columns and Table layouts, and in those layout, Edocman won't highlighted the searched keyword.
The last screenshot if the Search result of Joomla Search function, and Edocman will highlight the searched keyword in Results

The first 3 are from my site. The last one is from a public Joomla site. How do I get it to show and highlight the searched keyword on my site?

Hi John,
Please activate the Joomla Search module at frontend of your site. You can raise new ticket on category: Edocman and provide your site url with super admin account, i will check and publish the Search function at frontend of your site for you.

After your guidance, I got search context to work as desired.  However, 8 months and hundreds of documents later, I find that the search context is shown for most documents, but not all.  See attached picture for a composite for a search where the first item does not show context but items 3,4,& 5 do correctly show context.  Any idea on how to get context on the first two? 

Hi John,
I am not sure why the text with highlighted word aren't show in some of search result. But you can submit ticket and send your site url with super admin account, PHPMyadmin url and account. I will debug the issue for you
Thanks
