Filters

In charting, the most common method of filtering is by creating a filter for that chart specifically:

../_images/filter-top-chart.gif

Note

The ability to see the most frequent values as shown in the screenshot above may be only for higher tiers of subscription in the future.

Filter conditions

In each condition, there are three parts (the above screenshot is from the top of chart):

  1. The field to apply. This can be any field that you have added into Content Chimera.

  2. The operator.

  3. The value to compare.

These are the possible operators:

equals

regex

This is advanced, for those who know regular expressions. Values should have a delimeter at the front and end, like /-en$/

empty

∅

This will only match fields with no value. It will NOT match zeroes.

greater than

always true

TRUE

not empty

!∅

See note about zeroes vs. empties above.

contains

contains

Does this field (evaluated as a string) contain this value?

in set

in_set

For a field that is comma separated, is one of the comma-separated items this value?

in year†

in year and month†

between†

† These are only available in shared filters.

Where filters are used

Filters are used in two places:

  • Charting (restricting what content is represented in the chart)

  • Rules (defining what conditions

A third place is filtering what URLs get crawled, but this has not yet been exposed in the front end.

Note

There is a slight difference between how filters are applied in charting and rules. Charting filtering is applied in database queries and the rules are applied in memory.

Shared filters

Note

Before chart-specific filters were added in October 2022, the only kind of filter was a shared filter. Shared filters may become depricated. For now, you can use a shared filter that has already been created, but you cannot add a new shared filter.

Filters can also be shared. Shared filters are managed under advanced settings.

../_images/shared-vs-chart-specific-filters.png

This is an example of editing a shared filter:

../_images/filter-example.png

In the above example, there are two conditions (they both must be true for the filter to apply: 1) the folder = articles and 2) Has Tables = yes.

Note

Be careful with shared filters. Since they can be used across rules and charting, if you change a filter in one place it can affect the other.
