Note Filter

AnkiMorphs only analyzes and sorts cards that match at least one note filter; if you don't specify any note filters, then AnkiMorphs won't do anything, so this is a necessary step. This can seem overly complicated and overwhelming, but hopefully things will make sense after reading to the end of this page. This is really the heart of the add-on, and it has some powerful options (notably tags), so having a good understanding of note filters work might significantly improve how much you benefit from AnkiMorphs.

Each note filter contains:

• Note Type
• Tags (optional)
• Field
• Morphemizer
• Morph Priority
• Read & Modify (optional)

Note Type

To find a card's note type do the following:

1. Go to Browse
2. Find a card you want AnkiMorphs to analyze and sort
3. Right-click the card
4. Click Info
5. See Note Type

All the cards in my Japanese Sentences deck (and sub-decks) have the same note type, but that might not be the case for your decks.

Another thing you can do is look through the Note Types in the left sidebar and until you find the cards you are after.

Tags

You can further filter AnkiMorphs to only work on cards with a certain note type and with/without specific tag(s).

Let's use an example of having a note type: anime_sub2srs. The card break-down of the note type is the following:

• Total cards: 20K
• Cards with the tag demon-slayer: 6k
• Cards with the tag movie: 3k
• Cards with the tag fight-scene: 2k
• Cards that have both demon-slayer and movie tags: 1k

If you want all the 20K cards of note type anime_sub2srs then leave the tags empty (default):

If you want the 6K cards with the demon-slayer tag:

If you want the 1k cards that have both demon-slayer and movie tags, i.e. the intersection:

If you want the 8K cards that have either demon-slayer or movie tags, i.e. the union, then you have to create two note-filters like this:

If you want the 18K cards that don't have the fight-scene tag:

Field

This is the field on the card AnkiMorphs reads and analyzes, which is then used to sort the card.

1. Go to Browse
2. Find the note type in the left sidebar
3. Find the field you care about

In my case the field I'm interested in is Japanese

Note: Fields with complete sentences are preferable over fields that only have isolated words. The more context the morphemizers are given, the less likely they are to produce false positives.

Morphemizer

This is the tool AnkiMorphs uses to split text into morphs. See the installation section for how to add morphemizers.

AnkiMorphs comes bundled with two morphemizers: Simple Space Splitter and SSS + Punctuation. These morphemizers are very basic and do not perform any linguistic analysis, meaning they won't provide accurate lemmas. Therefore, you should only use them if no other morphemizers are available for your particular language.

Simple Space Splitter

As the name suggests, this morphemizer just splits words based on whitespace.

Simple Space Splitter + Punctuation

This morphemizer extends the Simple Space Splitter to preserve words containing hyphens (-) and apostrophes ('), ensuring that words like these are not split apart:

• mother-in-law
• quelqu'un

Note: This morphemizer may not work correctly for some languages, such as Arabic. If you encounter this issue, try using the Simple Space Splitter instead.

Morph Priority

The calculated score of the card, and as a result, the sorting of the card, depends on the priority you give the morphs. You can either set the priorities to be Collection frequency (how often the morphs occur in your card collection), or you could use a custom priority file that specifies the priorities of the morphs.

AnkiMorphs automatically finds .csv files placed in [anki profile folder]/priority-files/.

Note: using Collection frequency is not recommended because it can be volatile; if you make any changes to your cards (delete, suspend, move, etc.), then it can cause a cascade of sorting changes.

Read & Modify

If, for whatever reason, you don't want AnkiMorphs to read one of the note filters you have set up, then you can uncheck the Read option.

If you uncheck Modify, AnkiMorphs will analyze the specified fields of cards (and update the database of known morphs based on them), but won’t reorder or change the cards in any way.

Usage

There are some nuances that are important to be aware of when it comes to note filters:

Order of the note filters

Order matters. In the image above all the cards that have note type ankimorphs_sub2srs will have the text found in the Japanese field analyzed, and then those cards will be sorted based on the score of that text.

After those cards are analyzed and sorted then the next note filter will take effect: All the cards that have the note type Kanji will have the text found in the Front field analyzed and then those cards will be sorted based on the score of that text.

Overlapping filters

If a card matches multiple filters, then it will only be analyzed and sorted based on the first matching filter. Any subsequent filters will not analyze and sort the card.

If you were to do something like this:

Then the second filter would do nothing because all the cards would have already been used by the first filter.

If you find yourself in a situation where you have overlapping note filters, then there are two things you can do:

• Make the filters more restrictive by using tags
• Create a new note type.

Tip: All your cards should follow the minimum information principle, not only will that help you remember them better, but it might make the note filters less complicated.
