What is Metadata?
Metadata is accessory data captured about documents. For example, an email file will contain not just the text of the email, but also information about who sent and received the email, when and where the email was sent, and from what domain the email came from. Similarly, a Word file might contain metadata about who authored the text and when the file was last edited, among other information.
There are two main types of metadata fields: text fields and time/date fields.
Everlaw’s Metadata Search Term
To search across the metadata in your case, add the metadata search term into the query builder. There are two parameters, or fields, in the metadata search term. The first parameter allows you to specify which field you would like to search on (ex. “To”, “From”, “Author”).
The second parameter allows you to specify a particular value for the chosen field. If the metadata field is a text field, a drop-down list will appear displaying the top 25 most prevalent values for the field you selected. As you type into the input box, the displayed values will change to match your input. To the right of the values you will see an estimate of the number of documents that match that exact metadata search. You can also select “(No value)” to find documents that do not have any value for your selected metadata field.
What’s the difference between an exact and non-exact metadata search?
An exact search means you want the value for the metadata field you selected to be exactly the inputted string. Let’s take a look at an example to clarify:
If you were to search for “george” with the exact box (in the far right) unchecked, then the search will return documents whose “From” field value contains the word “george". This means that the search will return all the listed results in the screenshot above, and more.
If, instead, you ran the search with the exact box checked, the search will only return documents whose “From” field value is exactly that metadata value. For example, if you select “‘Townsend George’ email@example.com>”, the search will default to only looking for documents whose “From” field is exactly that string.
If you select an option from the drop-down list, the search will automatically default to an exact search.
You can tell that a search is an exact search because the word “exact” will be appended at the end of the search term. In this example below, the search is looking for documents whose “From” field is exactly “Blatchford James <JBlatchford@caiso.com>”.
You can also use wildcard characters when constructing searches for text-based metadata fields. Click here to find out more about wildcard searches.
Finally, just like with the content search term, inputting multiple terms or phrases separated by a space or comma will default to an OR search. This means you'll be searching for documents with metadata field values that match one or more of the inputted terms or phrases.

There are some unexpected fields in my dataset. Is there something special about metadata fields in Everlaw?
When documents are loaded into Everlaw, the system automatically detects semantically-related fields and groups them together under a single name (for example, fields like “Custodian”, “Custdn”, “CUST”, etc. will be grouped into the "Custodian" field). Searching a grouped field will search across all the fields grouped under that particular field name. This makes it much easier to search across documents with synonymous fields since they are now normalized. For more information about grouped and canonical fields, click here.
