How Mergeflow's search syntax works
Filter boxes are limited in width (imagine how long a filter box would be for a search query consisting of 20 terms combined by logical OR…). So if your query terms do not fit comfortably within the width limits of the filter box, clicking on the filter box opens a popup:
In the popup, you can add further search terms or delete existing ones. In the example above, we added 'tracrrna' (cf. red arrow) as a further search term. After clicking 'OK', all four search terms in the box will be combined by logical OR.
How to best build up a longer NOT search query
Besides AND, OR, and NOT searches, mergeflow also features a NEAR search. For example, a search for…
…only finds documents that contain “internet of things” and “analytics” with a maximum of five intervening words (NEAR2 would allow max. two intervening words, NEAR10 ten words, etc.). Sequence of the search terms plays no role here.
You can also combine NEAR searches by logical “OR”, for instance…
...finds documents that (1) contain “IoT” max. five words apart from “analytics”, or (2) “smart grid” max. three words apart from “analytics”.
