In General, Blogspot Search Summary page is the landing place where visitor searching some query within our search box with the suffix "/search?q=query". In Practice, Search Summary Result is found everywhere.
Label page has URL Formatted like "/search/label/LabelName" and is same as "/search?label=LabelName". And when we type "/search" without suffix, it will show all the article that we have.
Uncustomized Blogger template or the Old Blogger template, if we go to that area, basically it will show limited number of the Article in it. The problem comes if we don't have Jump Link in our article or we set article that has <!--more--> contained too much word. It will make our blog shown like an unlimited long page.
In this example, we want to make Snippets Summary or auto limit word of every post that is shown in Label or Searches Result, only wit the Blogger Expression Language, and not using any Javascript in it.
The Source Code
The code we want to use is split in two part. The first code is to make instruction call an inclusion with <b:include/> tag, and the second is the inclusion itself.

Guide How To Create Post Label Summary
Code above is only for Layout Version 1 and 2.
Adding Calling for Inclusion Code
> First backup your template.
> In Template editor, and find <b:include data='post' name='post'/> its inside Blog1 Widget main inclusion.
> Now replace with:
<b:if cond='data:view.isSearch'>
<b:include data='post' name='Blakbin-PostSummary'/>
<b:else/>
<b:include data='post' name='post'/>
</b:if>
> Adding the Inclusion
Find this code <b:includable id='main' var='top'> its in Blog1 Widget area, and then Copy and paste the inclusion code above, right "before" it.
> Our code now will look like
<b:includable id='PostSummary' var='post'>⋯</b:includable>
<b:includable id='main' var='top'>
> Save template and see the change in Label page and search page.
The Code Explanation
We know the inclusion call is only statement to call an 'PostSummary' inclusion. We replace the default code to include our inclusion call statement. It has condition if 'data:view.isSearch' this mean our post summary inclusion will be showing on any URL that has a /search. Its including Search Query page with an URL /search?q=keyword and Label page which URL is /search/label/labelname. We can replace the expression with one of this table below
| Expression | Meaning |
|---|---|
| 'data:view.isSearch' | Any URL contain a word 'search' |
| 'data:view.isLabelSearch' | An page showing only a post contain selected label |
| 'data:view.search.query' | An search result page based on search query |
Now its time to explain the content inside the inclusion.
> The code between <style> and </style> its the CSS code to make how our Post Summary look like.
> The Post Title Block
<div class='blakbin-result-title-wrapper'>
<div class='blakbin-result-title'>
<a expr:href='data:post.url'><data:post.title/></a>
</div>
</div>
This code is contain the Post title along with their post links. We give an expr: attribute to the HTML href attribute, so we can use Blogger data expression.
> The Image Thumbnail of the post
<b:if cond='data:view.featuredImage'>
<td class='blakbin-thumbnail'>
<div class='blakbin-thumbnail-image-box'>
<img style='max-width:unset;' expr:src='data:view.featuredImage resizeImage 72 resizeImage "1:1"'/>
</div>
</td>
</b:if>
With <b:if> Conditional tag, we define if the post have any image, then it will take the first image in the post as thumbnail. Also in this block we using resizeImage operator to resize the image to 72x72px.
> The Post Summary
Blogger , Tips and Tricks<div class='blakbin-desc-snippet'>
<span><b:eval expr='data:post.body snippet {length: 250, links: false, linebreaks: false}'/></span>
<span class='show-full-article'>
<a class='blakbin-button' expr:href='data:post.url'>Show Full Article</a>
</span>
</div>
In this part, we using <b:eval> tag to evaluate the post body with help of snippet operator we give limit to only show the first 250 character of the post article body, eliminate any link and a linebreak to be displayed in the summary, then give a Link to its article in the tail of the summary.
