Apache solr string or text?

The fields as default defined in the solr schema are vastly different String stores a word/sentence as an exact string without performing tokenization etc. Commonly useful for storing exact matches, e. G, for facetting Text typically performs tokenization, and secondary processing (such as lower-casing etc.). Useful for all scenarios when we want to match part of a sentence If the following sample This is a sample sentence is indexed to both fields we must search for exactly the text This is a sample sentence to get a hit from the string field, while it may suffice to search for sample (or even samples with stemmning enabled) to get a hit to get a hit from the text field.

– Rahul Aug 25 at 9:31 You will get a larger index size when tokenizing, how large depends on your processing chain. Index creation will also be marginally slower since there's more work. Index read/creation will be great either way, so don't worry about it unless approaching millions of documents.

– Johan Sjöberg Aug 25 at 9:37 I am reading through millions of documents..hope that is not a problem..so I am going for string field since it seems efficient in all cases AND I do not need tokenizers/full text search – Rahul Aug 25 at 10:47.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
