Is there anyway to filter the results by page title tag or certain meta tags... I read the documentation... but it's a mess :-( Is anybody have an idea??
回答1:
Yes, you can sort and filter on custom meta tags.
First, put the data you want to filter on into meta tags:
<meta name="color" value="blue">
Next, test that Google can find the tags by testing your URL with the Rich Snippet Tool Under the 'Structured data for filtering search results', you should see more:pagemap:metatags-color:blue.
Finally, query your custom search engine with the structured data string above. Putting more:pagemap:metatags-color:blue in the search box works, or use it with your query parameter (usually q) in the URL.
For numeric meta tags, you can sort with sort=more:pagemap:metatags-sales_rank (or whatever your attribute is).
To search on page title it should work to use Google's standard intitle: operator.
