Hi,

I want to be able to search for some properties that have some specials characters(#, !). The standard analyzer does not seem to work well for my use case can you suggest some analyzers that will work best.

Node properties example:

{
"identity": 588,
"labels": [
"SYS"
],
"properties": {
"name": "&{}CIT-GE",
"psId": "1232"
}
}

I want to be able to run some queries like the below.

call db.index.fulltext.queryNodes("TX_eucId_csiId_name_key","*#CIT*") yield node return node

thanks!

Hello @KD :blush:

I can't suggest any analyzer for you but you can get the full list with description and their stop words, maybe it can help you to choose. Otherwise, you will have to write your own analyzer.

CALL db.index.fulltext.listAvailableAnalyzers();

Thank you @Cobra . I will explore writing a custom analyzer.
