Adding a keyword

When you add a keyword or phrase, Amplified will automatically highlight matching text in your results and show a count of the number of exact matches in each result.

To add a keyword click on the field and type your keyword then press CommaEnter, or Tab. You will know the keyword has been created when it turns into a pill.

To remove a single keyword click the x  on the pill. You can use the x on the right side to remove all keywords from that color group.

To delete all of your keywords click on the ...  and select Remove all from the dropdown menu.

Using keywords for search

You can also use your keywords and phrases as filters so you only see results that include those keywords. Similarly, you can filter to exclude keywords.

By default, filters are off which means keywords are only used to highlight results not search. To search with keywords click the filter toggle to set it to ON to and then Update results. Clicking the toggle again will turn filters back OFF.

Amplified's keyword filters use automatic stemming for highlighting and searching. For example, when you write "meter" Amplified will automatically include meter, meters, metered, metering, etc. so you don't need to. However, the keyword highlight counts only reflect exact matches.

📝 Example: What happens if you add "meter" and a patent does not contain "meter" but does include "metered"? The patent will be included in your filtered results and you'll see "metered" in your relevant text snippets because of auto-stemming. However, the highlight count will still say 0 because no exact matches were found.

Boolean logic and highlighting in multiple colors

When you add more than one keyword Amplified will automatically apply Boolean logic and multi-color highlighting. 

  • To search for "light" or "sensor" create two pills in the same color:

  • To search for "light" and "sensor" create two pills in different colors:

  • To search for "light sensor" as a phrase enter the whole phrase as one pill:

Tip! We recommend organizing similar concepts and synonyms together in the same keyword color group.

How Boolean logic works in Amplified

When you add multiple keywords in the same line they will be highlighted in the same color and joined with OR logic. Enter keywords on the next line to create a new keyword color group. Those will be highlighted in a different color. Multiple keyword color groups are AND'd together for search.

Customize which text fields to search in

By default, keyword filters will look for matches in any part of the patent: title, abstract, description, or claims. You can see this because all of the boxes are checked for those fields.

To customize your filter to only include results that match your keyword on specific sections of the patent simply uncheck the fields you don't care about. For example, to only filter results with keywords in the claims, uncheck the Title, Abstract, and Description boxes but leave Claims checked.

The checkboxes only control search, not highlighting. You can uncheck all of the boxes to make a keyword group highlight only.


Amplified's keyword filters and highlighting support single and multi-character wildcards.

﹗Note: Wildcards can not be used with keyword phrases. For example "aug*" and "aug*","reality" will work but "aug* reality" will not.

  • Use * to represent an unlimited number of characters. You must enter at least three characters before a wildcard (i.e. abc* not ab*)
  • Use ? to represent a single wildcard character
  • You can use multiple ? to represent a fixed number of wildcard characters such as h???o or he???

Proximity filters

You can use a proximity operator highlight and filter for specific keywords that show up near each other. For example, "electric vehicle" may be too specific but "electric" and "vehicle" is too vague. In this example you can solve this problem with a proximity filter to look for results that have "electric" near "vehicle".

  • To only show results that include removable within 2 words of doser , write an uppercase W2 separated by spaces in between the two keywords you want to search
  • The number you write after the W is the number of words. You can search within 1 to 9 words. For example, W9 will look within 9 words. The order does not matter.

Query mode & Custom filters

For even more advanced searchers, check out our articles on Query mode. Query mode allows you to write command line queries with search history. You can use queries in your Explore pane by adding them as custom filters. This allows you to sort query results by AI. This is particularly helpful when the search needs a clearly defined scope such as monitors, FTO, and sometimes landscapes or portfolio analysis.
