Weird problem I cannot explain or solve!
On my production server queries can fail if one word changes. This is reliable. Its just the word change that triggers the error, not a fluke of unfortunate timing (i.e. the server is overloaded)
ES 7.8 with php APi 7.7
Search term: very long search term here and economic
Query sent as (php print_r output btw)
[query_string] => Array ( [fields] => Array (  => document_content  => case_summary^10 ) [query] => +very +long +search +term +here +and +economic ) )
BUT the query string
very long search term here and contains
very long search term here and continuity
very long search term here and children
Just changing one word causes the fail, continuity OK, children nope. (those pesky kids)
Any thoughts why this may be? I am bamboozled!
