Using keywords to highlight and filter

Add keyword or phrases to highlight and filter results

  1. Creating a keyword
  2. Using keywords to filter results
  3. Multiple keywords and Boolean logic
  4. Customize filters by field (title, abstract, description, claims)
  5. Advanced techniques: wildcards
  6. Advanced techniques: proximity search

Creating 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 that pill. You can also remove an entire line of keywords with the circled x. To delete all of your keywords click on the ... and select Remove all from the dropdown menu.

Using keywords to filter results

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. To filter with your keywords, click the filter results toggle to set it to ON and then click Update results. To turn the filters back off just click the toggle and hit the Update results button again.

﹗Note: Amplified's keyword filters use automatic stemming so when you write "meter" we will include meter, meters, metered, metering, etc. without you needing to write each one out or use a wildcard

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

Multi-highlight and boolean logic

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 color.
Add similar concepts in the same line to join them with OR logic and highlight in the same color. To add a different concept, enter keywords on the next line. Those will be highlighted in a different color and, when filtering, AND'd together with the previous line.

Customize filters by field

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 filters not highlighting. You'll always see highlights and counts from the whole patent. If you uncheck all of the boxes, then the keyword will continue to highlight but not filter at all. 


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.
