I use well above 3.000 notes for academic purposes. Unfortunately, if you have a lot of notes, the standard search feature performs really bad (I am aware of th eadvanced search capabilities). At the moment it looks like it only checks notes for the search word and ranks them according to the last edit. This is not sufficient. When I create a note, for instance, I often link other notes to that note. When I search for the title of the note, I get all those notes where I added the link first, because that was the last edit. It would be great if there were better ranking functionalities like giving more weight to linked notes or keywords that appear in the title. Additionally I would highly appreciate if a search for "topics" would also come up with a note titled "topic". From a technical side: At the moment it looks like a simple boolean retrieval algorithm is implemented with a ranking by "last edit" It would be great if the title would receive a higher weight. Documents with higher term frequencies should also receive a higher weight. The same accounts for linked notes. One could make use of the hyperlink strucuter using "Hypertext-Induced Topic Search" or something similar to "PageRank". Search words are not lemmatized. If I have a note titled "topic" there is no way to find it using search word "topics". Some kind of context search functionality like "Latent Semantic Indexing" might also be useful .
