[TYPO3-english] realurl search page and ver large tx_realurl_urlencodecache

[Jan Slusarczyk]

I have recently discovered that tx_realurl_urlencodecache grows 
enormously (240.000 rows, 910MB) on my install. It is being filled by 
variants of the same url - search page and get parameters containing 
phrases, filters etc. I'm using tx_solr for search and the variants I 
see are for example:

szukaj.html?no_cache=1&tx_solr%5Bfilter%5D%5B1%5D=pageHierarchy%253A%252FDzieci%2B6-9%252FSzko%25C5%2582a%252FNauka%2Bczytania%2Bbez%2Bstresowania 
szukaj.html?tx_solr%5Bq%5D=Anna%20Czajkowska&tx_solr%5Bsort%5D=title%20desc&tx_solr%5Bfilter%5D%5B0%5D=pageHierarchy%253A%252FDzieci%2B6-9%252FWychowanie&tx_solr%5Bfilter%5D%5B1%5D=pageHierarchy%253A%252FDzieci%2B6-9%252FWychowanie%252FAutorytarne%2Bwychowanie%2B%25E2%2580%2593%2B%25E2%2580%259Eto%2Bdla%2Btwojego%2Bdobra%25E2%2580%259D 

szukaj.html?no_cache=1&tx_solr%5Bfilter%5D%5B0%5D=pageHierarchy%253A%252FStyl%252FDobrze%2Bwygl%25C4%2585daj&tx_solr%5Bfilter%5D%5B1%5D=pageHierarchy%253A%252FStyl&tx_solr%5Bsort%5D=title%20asc

What should I do to my install to stop this growth?
