The card database portion of the companion app does not allow for the use of quotes to force a text search to exactly match the phrase being searched, while the website version DOES allow this. The companion app should be updated to allow this feature.

Ex. Searching for rules text formatted like: "when a creature enters" results in a search where any of those words appear on the card, not necessarily in that order. When searching for the same rules text and using quotes on the website you will only get cards with that exact phrase.
