Sort date-like words
Dates in word format are sorted alphabetically.
Meta Tags
The Google Search Appliance provides search parameters and special query terms that enable you to
leverage the meta tags that are available in your content. These make it possible to find matches
specifically in meta data content, rather than content occurring anywhere in the document.
There are no restrictions on the number of meta tag matches a results page can display.
The maximum number of characters for a metadata attr:value pair for the search request parameters
requiredfields and partialfields and special query term inmeta is 121. If the combination of the
metadata attr:value is bigger than 121 characters then those particular meta tag contents will be visible
at serving time although not searchable via the search request. Also, it will not be visible in dynamic
navigation.
Take note that if the metatada attr:value contains term values that have less than 121 characters, those
terms may still be searchable via the partialfields request parameter and the inmeta special query
term using the ~ operator (see the example below).
