Exercise 14.6 - Intro to Neo4j 4.0

[begloria_c3]

Note that as I go through the exercises, I am testing out "what if" scenarios. This exercise has two parts, asking for ('real OR world') and then also ('real AND world').

Alternatives:
Using ('real or world') works.
Using ('real' OR 'world') does not work. (errors)
Using ('real | world') works. (pipe substituted for 'or')
Using ('real and world') does not work. (same results as using 'or')

Also, I see that using toLower() or toUpper() are not needed in this context.

Would you please explain the logic behind each of these? Just looking for a deeper understanding.

Hello @begloria.c3

Sorry I missed your question.

Using ('real' OR 'world') does not work. (errors) has an extra ' in it is that why you get errors?

In order to understand how full-text schema indexes work, you need to understand how lucene searches work. They are not "intuitive".

I suggest you look here to better understand how lucene works:
