With
geo_pointfields, here is the special case of values that have a syntactically valid format, but the numerical values forlatitudeandlongitudeare out of range.If
ignore_malformedisfalse, an exception will be thrown as usual. But if it istrue, the document will be indexed correctly, by normalizing the latitude and longitude values into the valid range. The special_ignoredfield will not be set. The original source document will remain as before, but indexed values, doc-values and stored fields will all be normalized.Fixes #94807
This PR also adds a bunch of line-breaks to the geo-point.md file to make it easier to back-port this change to the 8.x branch. The line breaks have been chosen to mimic the original ASCIIDOC files, so the diff will be cleaner.
