Modified site info feed template to secure the description field against injected code. Also adjusted search service by extracting samples within the correct scope and including them in the returned site info. This improves the quality and security of the displayed information.
This change integrates the Feedlot RSS Bot with Marginalia's site info view to offer a preview of the latest updates.
The change introduces a new tiny feature that is a feedlot-client based on Java's HttpClient.
This is for filtering results on how many times the term appears on the domain. The intent is to be beneficial in creating e.g. a domain search feature. It's also very helpful when tracking down spammy domains.
We do both ip2location and ASN data.
The change also adds some keywords based on autonomous system information, on a somewhat experimental basis. It would be neat to be able to e.g. exclude cloud services or just e.g. cloudflare from the search results.
The code now intercepts and deals with potential exceptions during the parsing of search parameters. This is in response to constant bad requests from bots which were cluttering the logs. A catch clause is added that suppresses these errors and redirects to the base URL.
The site info view can't blindly assume that every website supports https. To figure out which schema to use when linking to a site, execute a single-result search for site:domain.name and then grab the schema off the result.
To allow this, a count parameter is introduced to doSiteSearch() in SearchOperator.
In this commit, GeoIP-related classes are refactored and relocated to a common library as they are shared across multiple services.
The crawler is refactored to enable the GeoIpBlocklist to use the new GeoIpDictionary as the base of its decisions.
The converter is modified ot query this data to add a geoip:-keyword to documents to permit limiting a search to the country of the hosting server.
The commit also adds due BY-SA attribution in the search engine footer for the source of the IP geolocation data.
This commit also fixes a bug in the loader where the IP field wouldn't always populate as intended, and refactors the DomainInformationService to use significantly fewer SQL queries.
The previous version used a personalized pagerank centering on a few academic domains, but this didn't work very well and most results were not very academia-centric.
This reduces the impact of restarting the search service, as the site information takes a few minutes to load during which it's not available. It also permits exposing this information via API in the future if there is interest in this.
The assistant service was also modified to do a late load of the suggestions trie, as this is a major contributor to its start-up time.
Finally, some changes were made to the client library, a new get() method was added that takes a TypeToken to allow deserialization of generics such as List<Foo>, and the scheduler was also modified to use virtual threads.
In the future this logic probably needs to move into a separate
service, as it's still quite slow to load. But this fixes response
times and DOS potential of previous version.
