This filter currently does not distinguish itself very much from the unfiltered results, and lends the impression that the filters don't "do anything".
It may come back in some shape or form in the future, with some additional tweaking of the rankings...
This change set updates the query APIs to enable the search service to add additional criteria, such as QueryStrategy and TemporalBias.
The QueryStrategy makes it possible to e.g. require a match is in the title of a result, and TemporalBias enables penalizing results that are not within a particular time period.
These options are added to the search interface. The old 'recent results' is modified to use TemporalBias, and a new filter 'Search In Title' is added as well.
The vintage filter is modified to add a temporal bias for the past.
Adds experimental support for clustering search results by e.g. domain. At a first stage, this is only enabled for the wiki and forum filters.
The commit also cleans up the UrlDetails class, which contained a number of vestigial entries.
Recent changes to the result ranking mean the no filter mode returns sufficiently good results for most queries that filtering by default just makes the search results more restricted.
!bang query handling seems to have fallen victim to an overzealous refactoring effort, and broken.
It's now repaired, and a test is in place to ensure we know if it breaks again.
Use a system.properties file to configure the system. This is loaded statically by MainClass or ProcessMainClass. Update the property names to be more consistent, and update the documentations to reflect the changes.
Several tests were manually running migrations in a large copy-paste blob of code. This makes the test less useful as it's possible to break the code while keeping the tests green by introducing a new migration that never gets run in the tests, and it's also difficult to reason about what the tests are doing.
A new test helper library is introduced with a TestMigrationLoader that can both run Flyway migrations, or load specific migrations in the cases a specific set of migrations need to be loaded. Existing tests are migrated to use the new code.
The changeset also makes the control service responsible for flyway migrations. This helps reduce the number of places the database configuration needs to be spread out. These automatic migrations can be disabled with -DdisableFlyway=true.
The commit also adds curl to the docker container, to enable docker health checks and interdependencies.
This was caused by incorrect usage of the renderInto() function, which was always buggy and should never be used. This method is removed with this change.

The EC_DOMAIN_LINK MariaDB table stores links between domains. This is problematic, as both updating and querying this table is very slow in relation to how small the data is (~10 GB). This slowness is largely caused by the database enforcing ACID guarantees we don't particularly need.
This changeset replaces the EC_DOMAIN_LINK table with a file in each index node containing 32 bit integer pairs corresponding to links between two domains. This file is loaded in memory in each node, and can be queried via the Query Service.
A migration step is needed before this file is created in each node. Until that happens, the actual data is loaded from the EC_DOMAIN_LINK table, but accessed as though it was a file.
The changeset also migrates/renames the links.db file to documents.db to avoid naming confusion between the two.
