Queries
Types
Strict
Use it when you are looking for the exact term.
By default, it is:
- Diacritic-Sensitive
- Case-Insensitive
- Matches partial words
You can always change the diacritic, case sensitivity, or whole word matching directly in the item settings.
Examples
Query: page
The pages are red
You can find that text on the same page
Page number 5
Query: canción
La cancion sonaba sin parar
Toca otra vez esa canción
Query: 😍
I love that song 😍
Regex
Use regular expressions to highlight.
ReadLayer supports ECMAScript Regex (JavaScript regular expressions) with support for Unicode (u flag).
The forward slash character / is used to denote the boundaries of the regular expression.
Don't add these to your regular expression. ReadLayer takes care of it.
Examples
Query: East Midlands|West Midlands|London
Goal: find any of the terms "East Midlands", "West Midlands", or "London".
The differences between the East Midlands and the West Midlands I only found out when I moved to Cov.
Query: (\p{N})+
Goal: find numbers
The current population increase is estimated at 67 million people per year
Page number 5
Query: \p{Sc}

Similar
Find similar terms or passages.
If you use double quotes ", ReadLayer will behave in the same way as with the Strict query.
You can combine strict and similar terms or sentences.
By default, this type of query will use your language settings defined in Settings > Language. However, you can fine tune each of your queries to use a different language. Once you have created a new item, adjust its language in the item settings.
Currently, ReadLayer finds related terms by inflection, not semantically.
Examples
Query: "miR-378"
Goal: find exact match
miR-378 suppresses the proliferation, migration and invasion of colon cancer cells by inhibiting SDAD1
Query: "miR-378" "SDAD1"
Goal: find passages where the terms "miR-378" and "SDAD1" are near each other
We found that miR-378 expression was low in colon cancer tissues and cell lines. Overexpression of miR-378 not only inhibits the proliferation of colon cancer cells in vitro by inducing apoptosis, but also inhibits migration and invasion by inhibiting the EMT of colon cancer cells.
SDAD1 is a direct target gene of miR-378. We also confirmed that miR-378 alleviated the malignant phenotypes of colon cancer cells by inhibiting the Wnt/β-catenin pathway. Conclusion: miR-378 inhibits the proliferation, migration and invasion of colon cancer cells by targeting SDAD1.
Query: "BORIS" regulation
Goal: Find the term "BORIS" near related terms to "regulation".
The evolution of epigenetic regulators CTCF and BORIS/CTCFL in amniotes.
This indicates that BORIS might have important regulatory roles in tumor immortalization during tumorigenesis.
Query: fire weld arrest
Goal: Find passages that talk about the people arrested for starting a fire by welding
